I'm using perl just because perl is _the_ classic language for text
processing jobs like that one and I've already hacked up perl scripts
before python started to exist ;)
These days every programming language on earth has bindings for the PCRE
library, so switching to something else should be possible without too
much trouble. It wouldn't be /me writing that script though.
I don't think adding perl as build dependency is a big problem, almost
everyone has it on the machine anyway. Try "rpm -e perl" on any linux
distro and watch the error message with the long list of stuff which
depends on perl.
Wrt. readability of the scripts: That is IMO more a matter of the
programming style than of the programming language. Sure you can easily
write unreadable perl code, but you don't have to. And you better
shouldn't, just in case you have to touch the scripts again one year later.
cheers,
Gerd
