The "tarball" command:
Usage: fossil tarball VERSION OUTPUTFILE [OPTIONS]
Generate a compressed tarball for a specified version. If the --name
option is used, its argument becomes the name of the top-level directory
in the resulting tarball. If --name is omitted, the top-level directory
name is derived from the project name, the check-in date and time, and
the artifact ID of the check-in.
The GLOBLIST argument to --exclude and --include can be a comma-separated
list of glob patterns, where each glob pattern may optionally be enclosed
in "..." or '...' so that it may contain commas. If a file matches both
--include and --exclude then it is excluded.
-X|--exclude GLOBLIST Comma-separated list of GLOBs of files to exclude
--include GLOBLIST Comma-separated list of GLOBs of files to include
--name DIRECTORYNAME The name of the top-level directory in the archive
-R REPOSITORY Specify a Fossil repository
