- * Arguments: @const char *va, *vb@ = two version strings
- *
- * Returns: Less than, equal to, or greater than zero, according to
- * whether @va@ is less than, equal to, or greater than @vb@.
- *
- * Use: Compares version number strings.
- *
- * The algorithm is an extension of the Debian version
- * comparison algorithm. A version number consists of three
- * components:
- *
- * [EPOCH :] MAIN [- SUB]
- *
- * The MAIN part may contain colons or hyphens if there is an
- * EPOCH or SUB, respectively. Version strings are compared
- * componentwise: first epochs, then main parts, and finally
- * subparts.
- *
- * The component comparison is done as follows. First, the
- * initial subsequence of nondigit characters is extracted from
- * each string, and these are compared lexicographically, using
- * ASCII ordering, except that letters precede non-letters. If
- * both are the same, an initial sequence of digits is extracted
- * from the remaining parts of the version strings, and these
- * are compared numerically (an empty sequence being considered
- * to have the value zero). This process is repeated until we
- * have a winner or until both strings are exhausted.
