version-compare VER1 VER2 #!optional TAIL-ZERO?procedure

Returns a negative, zero, or positive integer representing the relative order of VER1 and VER2. Compares number & string elements natively, but in a comparison between a number & a string element, the string always takes precedence. Thus "1.a.2" < "a.1.2".

semantic-version ; version 1 to compare.
semantic-version ; version 2 to compare.
boolean ; ignore trailing 0's?

Orders versions in the same manner as the chicken-install tool.
