Versions, revisions and releases
================================

   A file can have several versions, as described above.  Likewise, a
software product can have several versions.  A software product is
often given a version number such as `4.1.1'.

   Versions in the first sense are called "revisions" in this document,
and versions in the second sense are called "releases".  To avoid
confusion, the word "version" is almost never used in this document.
