ActiveState::Version - Utility functions for version comparison

```
use ActiveState::Version qw(vgt veq vcmp);
my $x = "0.9.9_beta";
my $y = "0.10";
my $z = "0.1";
print "$x is ", (vgt($x, y) ? "greater" : "less or equal"), "than $y.\n";
print "$y and $z are ", (veq($y, $z) ? "" : " not "), "equal.\n";
my @sorted = sort { vcmp($a, $b) } ($x, $y, $z);
print "The newest version is $sorted[-1].\n";
```

Handy utilities for uniform version comparison across various ActiveState applications.

Provides `vcmp`

, `vge`

, `vgt`

, `vle`

, `vlt`

, `veq`

, all of which perform comparisons equivalent to the similarly named perl operators.

Also provides the `vnumify`

function which turns any version string to a floating point number. For version strings that are gibberish it returns 0.
