** COMMAND: all
**
** Usage: %fossil all (list|ls|pull|push|rebuild|sync)
**
** The ~/.fossil file records the location of all repositories for a
** user. This command performs certain operations on all repositories
** that can be useful before or after a period of disconnected operation.
**
** On Win32 systems, the file is named "_fossil" and is located in
** %LOCALAPPDATA%, %APPDATA% or %HOMEPATH%.
**
** Available operations are:
**
** ignore Arguments are repositories that should be ignored
** by subsequent list, pull, push, rebuild, and sync.
**
** list | ls Display the location of all repositories.
** The --ckout option causes all local checkouts to be
** list instead.
**
** changes Shows all local checkouts that have uncommitted changes
**
** pull Run a "pull" operation on all repositories
**
** push Run a "push" on all repositories
**
** rebuild Rebuild on all repositories
**
** sync Run a "sync" on all repositories
**
** Repositories are automatically added to the set of known repositories
** when one of the following commands are run against the repository: clone,
** info, pull, push, or sync. Even previously ignored repositories are
** added back to the list of repositories by these commands.
