	@AUTOREMAKE@

# Automatically reconfigure whenever an autosetup file or one of the
# make source files change.
#
# The "touch" is necessary to avoid a make loop due to a new upstream
# feature in autosetup (GH 0a71e3c3b7) which rewrites *.in outputs only
# if doing so will write different contents; otherwise, it leaves them
# alone so the mtime doesn't change.  This means that if you change one
# our depdendencies besides Makefile.in, we'll reconfigure but Makefile
# won't change, so this rule will remain out of date, so we'll reconfig
# but Makefile won't change, so we'll reconfig but... endlessly.
#
# This is also why we repeat the reconfig target's command here instead
# of delegating to it with "$(MAKE) reconfig": having children running
# around interfering makes this failure mode even worse.

/*
** COMMAND: settings
** COMMAND: unset*
**
** Usage: %fossil settings ?SETTING? ?VALUE? ?OPTIONS?
**    or: %fossil unset SETTING ?OPTIONS?
**
** The "settings" command with no arguments lists all settings and their
** values.  With just a SETTING name it shows the current value of that setting.
** With a VALUE argument it changes the property for the current repository.
**
** Settings marked as versionable are overridden by the contents of the
** file named .fossil-settings/PROPERTY in the check-out root, if that
** file exists.
**
** The "unset" command clears a setting.
**
** Settings can have both a "local" repository-only value and "global" value
** that applies to all repositories.  The local values are stored in the
** "config" table of the repository and the global values are stored in the
** $HOME/.fossil file on unix or in the %LOCALAPPDATA%/_fossil file on Windows.
** If both a local and a global value exists for a setting, the local value
** takes precedence.  This command normally operates on the local settings.
** Use the --global option to change global settings.

**   --global   set or unset the given property globally instead of
**              setting or unsetting it for the open repository only.

/*
** COMMAND: settings
** COMMAND: unset*
**
** Usage: %fossil settings ?PROPERTY? ?VALUE? ?OPTIONS?
**    or: %fossil unset PROPERTY ?OPTIONS?
**
** The "settings" command with no arguments lists all properties and their
** values.  With just a property name it shows the value of that property.
** With a value argument it changes the property for the current repository.
**
** Settings marked as versionable are overridden by the contents of the
** file named .fossil-settings/PROPERTY in the check-out root, if that
** file exists.
**
** The "unset" command clears a property setting.
**
**
**    access-log       If enabled, record successful and failed login attempts
**                     in the "accesslog" table.  Default: off
**
**    admin-log        If enabled, record configuration changes in the
**                     "admin_log" table.  Default: off
**
**    allow-symlinks   If enabled, don't follow symlinks, and instead treat
**     (versionable)   them as symlinks on Unix. Has no effect on Windows
**                     (existing links in repository created on Unix become
**                     plain-text files with link destination path inside).
**                     Default: on (Unix), off (Windows)
**
**    auto-captcha     If enabled, the Login page provides a button to
**                     fill in the captcha password.  Default: on
**
**    auto-hyperlink   Use javascript to enable hyperlinks on web pages
**                     for all users (regardless of the "h" privilege) if the
**                     User-Agent string in the HTTP header look like it came
**                     from real person, not a spider or bot.  Default: on
**
**    auto-shun        If enabled, automatically pull the shunning list
**                     from a server to which the client autosyncs.
**                     Default: on
**
**    autosync         If enabled, automatically pull prior to commit
**                     or update and automatically push after commit or
**                     tag or branch creation.  If the value is "pullonly"
**                     then only pull operations occur automatically.
**                     Default: on
**
**    autosync-tries   If autosync is enabled setting this to a value greater
**                     than zero will cause autosync to try no more than this
**                     number of attempts if there is a sync failure.
**                     Default: 1
**
**    binary-glob      The VALUE is a comma or newline-separated list of
**     (versionable)   GLOB patterns that should be treated as binary files
**                     for committing and merging purposes.  Example: *.jpg
**
**    case-sensitive   If TRUE, the files whose names differ only in case
**                     are considered distinct.  If FALSE files whose names
**                     differ only in case are the same file.  Defaults to
**                     TRUE for unix and FALSE for Cygwin, Mac and Windows.
**
**    clean-glob       The VALUE is a comma or newline-separated list of GLOB
**     (versionable)   patterns specifying files that the "clean" command will
**                     delete without prompting or allowing undo.
**                     Example: *.a,*.lib,*.o
**
**    clearsign        When enabled, fossil will attempt to sign all commits
**                     with gpg.  When disabled (the default), commits will
**                     be unsigned.  Default: off
**
**    crlf-glob        A comma or newline-separated list of GLOB patterns for
**     (versionable)   text files in which it is ok to have CR, CR+LF or mixed
**                     line endings. Set to "*" to disable CR+LF checking.
**                     The crnl-glob setting is a compatibility alias.
**
**    default-perms    Permissions given automatically to new users.  For more
**                     information on permissions see Users page in Server
**                     Administration of the HTTP UI. Default: u.
**
**    diff-binary      If TRUE (the default), permit files that may be binary
**                     or that match the "binary-glob" setting to be used with
**                     external diff programs.  If FALSE, skip these files.
**
**    diff-command     External command to run when performing a diff.
**                     If undefined, the internal text diff will be used.
**
**    dont-push        Prevent this repository from pushing from client to
**                     server.  Useful when setting up a private branch.
**

**     (versionable)   update and checkout commands, if no file or directory
**                     exists with that name, an empty directory will be
**                     created.
**
**    encoding-glob    The VALUE is a comma or newline-separated list of GLOB
**     (versionable)   patterns specifying files that the "commit" command will
**                     ignore when issuing warnings about text files that may
**                     use another encoding than ASCII or UTF-8. Set to "*"
**                     to disable encoding checking.
**
**    exec-rel-paths   When executing certain external commands (e.g. diff and
**                     gdiff), use relative paths.
**
**    gdiff-command    External command to run when performing a graphical
**                     diff. If undefined, text diff will be used.
**
**    gmerge-command   A graphical merge conflict resolver command operating
**                     on four files.
**                     Ex: kdiff3 "%baseline" "%original" "%merge" -o "%output"
**                     Ex: xxdiff "%original" "%baseline" "%merge" -M "%output"
**                     Ex: meld "%baseline" "%original" "%merge" "%output"
**
**    hash-digits      The number of hexadecimal digits of the SHA1 hash to
**                     display.  (Default: 10; Minimum: 6)
**
**    http-port        The TCP/IP port number to use by the "server"
**                     and "ui" commands.  Default: 8080
**
**    https-login      Send login credentials using HTTPS instead of HTTP
**                     even if the login page request came via HTTP.
**
**    ignore-glob      The VALUE is a comma or newline-separated list of GLOB
**     (versionable)   patterns specifying files that the "add", "addremove",
**                     "clean", and "extra" commands will ignore.
**                     Example:  *.log customCode.c notes.txt
**
**    keep-glob        The VALUE is a comma or newline-separated list of GLOB
**     (versionable)   patterns specifying files that the "clean" command will
**                     keep.
**
**    localauth        If enabled, require that HTTP connections from
**                     127.0.0.1 be authenticated by password.  If
**                     false, all HTTP requests from localhost have
**                     unrestricted access to the repository.
**
**    main-branch      The primary branch for the project.  Default: trunk
**
**    manifest         If set to a true boolean value, automatically create
**     (versionable)   files "manifest" and "manifest.uuid" in every checkout.
**                     Optionally use combinations of characters 'r'
**                     for "manifest", 'u' for "manifest.uuid" and 't' for
**                     "manifest.tags".  The SQLite and Fossil repositories
**                     both require manifests.  Default: off.
**
**    max-loadavg      Some CPU-intensive web pages (ex: /zip, /tarball, /blame)
**                     are disallowed if the system load average goes above this
**                     value.  "0.0" means no limit.  This only works on unix.
**                     Only local settings of this value make a difference since
**                     when running as a web-server, Fossil does not open the
**                     global configuration database.
**
**    max-upload       A limit on the size of uplink HTTP requests.  The
**                     default is 250000 bytes.
**
**    mtime-changes    Use file modification times (mtimes) to detect when
**                     files have been modified.  (Default "on".)
**
**    mv-rm-files      If enabled (and Fossil was compiled with legacy "mv/rm"
**                     support), the "mv" and "rename" commands will also move
**                     the associated files within the checkout -AND- the "rm"
**                     and "delete" commands will also remove the associated
**                     files from within the checkout.  Default: off.
**
**    pgp-command      Command used to clear-sign manifests at check-in.
**                     The default is "gpg --clearsign -o ".
**
**    proxy            URL of the HTTP proxy.  If undefined or "off" then
**                     the "http_proxy" environment variable is consulted.
**                     If the http_proxy environment variable is undefined
**                     then a direct HTTP connection is used.
**
**    relative-paths   When showing changes and extras, report paths relative
**                     to the current working directory.  Default: "on"
**
**    repo-cksum       Compute checksums over all files in each checkout
**                     as a double-check of correctness.  Defaults to "on".
**                     Disable on large repositories for a performance
**                     improvement.
**
**    self-register    Allow users to register themselves through the HTTP UI.
**                     This is useful if you want to see other names than
**                     "Anonymous" in e.g. ticketing system. On the other hand
**                     users can not be deleted. Default: off.
**
**    ssh-command      Command used to talk to a remote machine with
**                     the "ssh://" protocol.
**
**    ssl-ca-location  The full pathname to a file containing PEM encoded
**                     CA root certificates, or a directory of certificates
**                     with filenames formed from the certificate hashes as
**                     required by OpenSSL.
**                     If set, this will override the OS default list of
**                     OpenSSL CAs. If unset, the default list will be used.
**                     Some platforms may add additional certificates.
**                     Checking your platform behaviour is required if the
**                     exact contents of the CA root is critical for your
**                     application.
**
**    ssl-identity     The full pathname to a file containing a certificate
**                     and private key in PEM format. Create by concatenating
**                     the certificate and private key files.
**                     This identity will be presented to SSL servers to
**                     authenticate this client, in addition to the normal
**                     password authentication.
**
**    tcl              If enabled (and Fossil was compiled with Tcl support),
**                     Tcl integration commands will be added to the TH1
**                     interpreter, allowing arbitrary Tcl expressions and
**                     scripts to be evaluated from TH1.  Additionally, the Tcl
**                     interpreter will be able to evaluate arbitrary TH1
**                     expressions and scripts. Default: off.
**
**    tcl-setup        This is the setup script to be evaluated after creating
**     (versionable)   and initializing the Tcl interpreter.  By default, this
**                     is empty and no extra setup is performed.
**
**    th1-docs         WARNING: If enabled (and Fossil was compiled with TH1
**                     support for embedded documentation files), this allows
**                     embedded documentation files to contain arbitrary TH1
**                     scripts that are evaluated on the server.  If native
**                     Tcl integration is also enabled, this setting has the
**                     potential to allow anybody with check-in privileges to
**                     do almost anything that the associated operating system
**                     user account could do.  Extreme caution should be used
**                     when enabling this setting.  Default: off.
**
**    th1-hooks        If enabled (and Fossil was compiled with support for TH1
**                     hooks), special TH1 commands will be called before and
**                     after any Fossil command or web page. Default: off.
**
**    th1-setup        This is the setup script to be evaluated after creating
**     (versionable)   and initializing the TH1 interpreter.  By default, this
**                     is empty and no extra setup is performed.
**
**    th1-uri-regexp   Specify which URI's are allowed in HTTP requests from
**     (versionable)   TH1 scripts.  If empty, no HTTP requests are allowed
**                     whatsoever.  The default is an empty string.
**
**    uv-sync          If true, automatically send unversioned files as part
**                     of a "fossil clone" or "fossil sync" command.  The
**                     default is false, in which case the -u option is
**                     needed to clone or sync unversioned files.
**
**    web-browser      A shell command used to launch your preferred
**                     web browser when given a URL as an argument.
**                     Defaults to "start" on windows, "open" on Mac,
**                     and "firefox" on Unix.
**
** Options:
**   --global   set or unset the given property globally instead of
**              setting or unsetting it for the open repository only.
**
**   --exact    only consider exact name matches.

/*
** COMMAND: annotate
** COMMAND: blame
** COMMAND: praise
**
** Usage: %fossil annotate|blame|praise ?OPTIONS? FILENAME
**
** Output the text of a file with markings to show when each line of the file
** was last modified.  The version currently checked out is shown by default.
** Other versions may be specified using the -r option.  The "annotate" command
** shows line numbers and omits the username.  The "blame" and "praise" commands
** show the user who made each check-in.
**
** Reverse Annotations:  Normally, these commands look at versions of
** FILENAME moving backwards in time back toward the root check-in, and
** thus the output shows the most recent change to each line.  However,
** if the -o|--origin option is used to specify some future check-in
** (example: "-o trunk") then these commands show changes moving towards
** that alternative origin.  Thus using "-o trunk" on an historical version
** of the file shows the first time each line in the file was been changed
** by subsequent check-ins.
**
** Options:
**   --filevers                  Show file version numbers rather than
**                               check-in versions
**   -r|--revision VERSION       The specific check-in containing the file
**   -l|--log                    List all versions analyzed
**   -n|--limit LIMIT            Limit the amount of analysis:
**                                 N      Up to N versions
**                                 Xs     As much as possible in X seconds
**                                 none   No limit
**   -o|--origin VERSION         The origin check-in. By default this is the
**                                 root of the repository. Set to "trunk" or
**                                 similar for a reverse annotation.

**   -w|--ignore-all-space       Ignore white space when comparing lines
**   -Z|--ignore-trailing-space  Ignore whitespace at line end

# Markdown Overview #

## Paragraphs ##

> Paragraphs are divided by blank lines.  
> End a line with two or more spaces to force a mid-paragraph line break.

## Headings ##

    # Top Level Heading                 Alternative Top Level Heading
    # Top Level Heading Variant #       =============================
>
    ## 2nd Level Heading                Alternative 2nd Level Heading
    ## 2nd Level Heading Variant ##     -----------------------------
>
    ### 3rd Level Heading               ### 3rd Level Heading Variant ###
    #### 4th Level Heading              #### 4th Level Heading Variant ####
    ##### 5th Level Heading             ##### 5th Level Heading Variant #####
    ###### 6th Level Heading            ###### 6th Level Heading Variant ######

## Links ##

> 1.  **\[display text\]\(URL\)**
> 2.  **\[display text\]\(URL "Title"\)**
> 3.  **\[display text\]\(URL 'Title'\)**
> 4.  **\<URL\>**

## Tables ##

>
    | Header 1     | Header 2    | Header 3      |
    ----------------------------------------------
    | Row 1 Col 1  | Row 1 Col 2 | Row 1 Col 3   |
    |:Left-aligned |:Centered   :| Right-aligned:|
    |              | ← Blank   → |               |
    | Row 4 Col 1  | Row 4 Col 2 | Row 4 Col 3   |

> The first row is a header if followed by a horizontal rule or a blank line.

> Placing **:** at the left, both, or right sides of a cell gives left-aligned,
> centered, or right-aligned text, respectively.  By default, header cells are
> centered, and body cells are left-aligned.

> The leftmost **\|** is required if the first column contains at least one
> blank cell.  The rightmost **\|** is optional.

## Miscellaneous ##

> *   In-line images are made using **\!\[alt-text\]\(image-URL\)**.
> *   Use HTML for advanced formatting such as forms.
> *   **\<!--** HTML-style comments **-->** are supported.
> *   Escape special characters (ex: **\[** **\(** **\|** **\***)
>     using backslash (ex: **\\\[** **\\\(** **\\\|** **\\\***).
> *   A line consisting of **---**, **\*\*\***, or **\_\_\_** is a horizontal
>     rule.  Spaces and extra **-**/**\***/**_** are allowed.
> *   See [daringfireball.net][] for additional information.
> *   See this page's [Markdown source](/md_rules?txt=1) for complex examples.

## Special Features For Fossil ##

> *  In hyperlinks, if the URL begins with **/** then the root of the Fossil
>    repository is prepended.  This allows for repository-relative hyperlinks.
> *  For documents that begin with a top-level heading (ex: **# heading #**),
>    the heading is omitted from the body of the document and becomes the
>    document title displayed at the top of the Fossil page.

*******************************************************************************
**
** This utility program scans Fossil source text looking for specially
** formatted comments and generates C source code for constant tables
** that define the behavior of commands, webpages, and settings.


**
** The source code is scanned for comment lines of the form:
**
**       WEBPAGE:  /abc/xyz
**       COMMAND:  cmdname
**       SETTING:  access-log
**
** The WEBPAGE and COMMAND comments should be followed by a function that
** implements the webpage or command.  The form of this function is:

**
**       void function_name(void){



**
** Command names can divided into three classes:  1st-tier, 2nd-tier,
** and test.  1st-tier commands are the most frequently used and the
** ones that show up with "fossil help".  2nd-tier are seldom-used and/or
** legacy command.  Test commands are unsupported commands used for testing
** and analysis only.
**
................................................................................
** with a "*" character, it is second tier.  Examples:
**
**        COMMAND:  abcde*
**        COMMAND:  fghij        2nd-tier
**        COMMAND:  test-xyzzy
**        COMMAND:  xyzzy        test
**
** A SETTING: may be followed by arguments that give additional attributes
** to that setting:
**
**        SETTING:  clean-blob   versionable width=40 block-text
**        SETTING:  auto-shun    boolean default=on
**
** New arguments may be added in future releases that set additional
** bits in the eCmdFlags field.
**
** Additional lines of comment after the COMMAND: or WEBPAGE: or SETTING:
** become the built-in help text for that command or webpage or setting.
**
** Multiple COMMAND: entries can be attached to the same command, thus
** creating multiple aliases for that command.  Similarly, multiple
** WEBPAGE: entries can be attached to the same webpage function, to give
** that page aliases.
**
** For SETTING: entries, the default value for the setting can be specified
** using a default=VALUE argument if the default contains no spaces.  If the
** default value does contain spaces, use a separate line like this:
**
**        SETTING: pgp-command
**        DEFAULT: gpg --clearsign -o
**
** If no default is supplied, the default is assumed to be an empty string
** or "off" in the case of a boolean.

*******************************************************************************
**
** This program scans Fossil source code files looking for special
** comments that indicate a command-line command or a webpage.  This
** routine collects information about these entry points and then
** generates (on standard output) C code used by Fossil to dispatch
** to those entry points.
**
** The source code is scanned for comment lines of the form:
**
**       WEBPAGE:  /abc/xyz
**       COMMAND:  cmdname

**
** These comment should be followed by a function definition of the

** form:
**
**       void function_name(void){
**
** This routine creates C source code for a constant table that maps
** command and webpage name into pointers to the function.
**
** Command names can divided into three classes:  1st-tier, 2nd-tier,
** and test.  1st-tier commands are the most frequently used and the
** ones that show up with "fossil help".  2nd-tier are seldom-used and/or
** legacy command.  Test commands are unsupported commands used for testing
** and analysis only.
**
................................................................................
** with a "*" character, it is second tier.  Examples:
**
**        COMMAND:  abcde*
**        COMMAND:  fghij        2nd-tier
**        COMMAND:  test-xyzzy
**        COMMAND:  xyzzy        test
**






** New arguments may be added in future releases that set additional
** bits in the eCmdFlags field.
**
** Additional lines of comment after the COMMAND: or WEBPAGE: become
** the built-in help text for that command or webpage.
**
** Multiple COMMAND: entries can be attached to the same command, thus
** creating multiple aliases for that command.  Similarly, multiple
** WEBPAGE: entries can be attached to the same webpage function, to give
** that page aliases.

  @ including user "nobody", as long as (1) the User-Agent string in the

  @ HTTP header indicates that the request is coming from an actual human

  @ being and not a robot or spider and (2) the user agent is able to
  @ run Javascript in order to set the href= attribute of hyperlinks.  Bots
  @ and spiders can forge a User-Agent string that makes them seem to be a
  @ normal browser and they can run javascript just like browsers.  But most
  @ bots do not go to that much trouble so this is normally an effective
  @ defense.<p>
  @


  @ <p>You do not normally want a bot to walk your entire repository because
  @ if it does, your server will end up computing diffs and annotations for
  @ every historical version of every file and creating ZIPs and tarballs of
  @ every historical check-in, which can use a lot of CPU and bandwidth
  @ even for relatively small projects.</p>
  @

  @ <p>Hyperlinks for user "nobody" are normally enabled as soon as the page
  @ finishes loading.  But the first check-box below can be set to require mouse
  @ movement before enabling the links. One can also set a delay prior to enabling

**   syncFlags is either SQLITE_SYNC_NORMAL (0x02) or SQLITE_SYNC_FULL (0x03).
**   syncFlags is used for rollback mode.  walSyncFlags is used for WAL mode
**   and contains the flags used to sync the checkpoint operations in the
**   lower two bits, and sync flags used for transaction commits in the WAL
**   file in bits 0x04 and 0x08.  In other words, to get the correct sync flags
**   for checkpoint operations, use (walSyncFlags&0x03) and to get the correct
**   sync flags for transaction commit, use ((walSyncFlags>>2)&0x03).  Note
**   that with synchronous=NORMAL in WAL mode, transaction commit is not synced
**   meaning that the 0x04 and 0x08 bits are both zero.
