Another use: Cons
and Cook,
two alternatives to Make,
uses MD5 signatures to determine if the contents of a source
file have changed since the last time a build was performed.
This makes builds a lot more reliable than Make's use of
file timestamps.
If anyone does care to look at code to see how the MD5 internals work, there's a Digest::Perl::MD5 module that implements the algorithm in pure Perl.
