/* DESCRIPTION
/* .nf
/*
* Version of this program. Official versions are called a.b.c, and
* snapshots are called a.b-yyyymmdd, where a=major release number, b=minor
* release number, c=patchlevel, and yyyymmdd is the release date:
* yyyy=year, mm=month, dd=day.
*
* Patches change both the patchlevel and the release date. Snapshots have no
* patchlevel; they change the release date only.
