The "add" command:

Usage: fossil add ?OPTIONS? FILE1 ?FILE2 ...?

Make arrangements to add one or more files or directories to the
current checkout at the next commit.

When adding files or directories recursively, filenames that begin
with "." are excluded by default.  To include such files, add
the "--dotfiles" option to the command-line.

The --ignore option is a comma-separate list of glob patterns for files
to be excluded.  Example:  '*.o,*.obj,*.exe'  If the --ignore option
does not appear on the command line then the "ignore-glob" setting is
used.

The --case-sensitive option determines whether or not filenames should
be treated case sensitive or not. If the option is not given, the default
depends on the global setting, or the operating system default, if not set.

Options:

   --case-sensitive <BOOL> override case-sensitive setting
   --dotfiles              include files beginning with a dot (".")   
   --ignore <CSG>          ignore files matching patterns from the 
                           comma separated list of glob patterns.
