**
** Return values:
**       0: ok

/*
** COMMAND: describe
**
** Usage: %fossil describe ?VERSION? ?OPTIONS?
**
** Provide a description of the given VERSION by showing a non-propagating
** tag of the youngest tagged ancestor, followed by the number of commits
** since that, and the short hash of VERSION.  Only tags applied to a single

** check-in are considered.
**
** If no VERSION is provided, describe the current checked-out version.
**
** If VERSION and the found ancestor refer to the same commit, the last two
** components are omitted, unless --long is provided.  When no fitting tagged
** ancestor is found, show only the short hash of VERSION.
**
** Options:
**
**    --digits           Display so many hex digits of the hash 
**                       (default: the larger of 6 and the 'hash-digit' setting)
**    -d|--dirty         Show whether there are changes to be committed
**    --long             Always show all three components
**    --match GLOB       Consider only non-propagating tags matching GLOB
