Fossil

/*
** COMMAND: wiki
**
** Usage: %fossil wiki (export|commit|list) WikiName
**
** Run various subcommands to fetch wiki entries.
**
**     %fossil wiki export PAGENAME
**
**        Sends the latest version of the PAGENAME wiki
**        entry to stdout.
**
**     %fossil wiki commit PAGENAME ?FILE?
**
**        Commit changes to a wiki page from FILE or from standard.
**
**     %fossil wiki create PAGENAME ?FILE?
**
................................................................................
**     %fossil wiki list
**
**        Lists all wiki entries, one per line, ordered
**        case-insentively by name.
**
** TODOs:
**
**     %fossil wiki export ?UUID? ?-f outfile[=stdout]? WikiName
**
**        Outputs the selected version of WikiName to the selected file.
**
**     %fossil wiki delete ?-m MESSAGE? WikiName
**
**        The same as deleting a file entry, but i don't know if fossil
**        supports a commit message for Wiki entries.
**
**     %fossil wiki ?-u? ?-d? ?-s=[|]? list
**
**        Lists the UUID and/or Date of last change for each entry, delimited
**        by the -s char.
**
**     %fossil wiki commit ?-f infile[=stdin]? WikiName
**
**        Commit changes to a wiki page from a file or standard input.
**        It creats a new entry if needed (or is that philosophically
**        wrong?).
**
**     %fossil wiki diff ?UUID? ?-f infile[=stdin]? EntryName
**
**        Diffs the local copy of a page with a given version (defaulting
**        to the head version).
