Feature request: configuration file

[hoelzro]

I think perlbrew's usefulness would be further enhanced by a configuration file; one could even leverage the existing Conf.pm that is used for mirror selection. This could come in handy if I want to make sure all the perl environments I install have a certain set of compilation flags; for example -Doptimize=-O2 -Dman1dir=' ' -Dman3dir=' '. I know I could accomplish this with shell aliasing, but then I'd lose those settings if I ran perlbrew from within a script.

Also, I think that the settings for a build could be organized into profiles; that way, I could have a default profile with the example settings from above, and a debug profile with debugging enabled in the interpreter and using Perl's malloc for Devel::Peek::mstat. If I wanted to install a Perl interpreter for version 5.8.9 for debugging, I could simply do this:

perlbrew install --profile debugging perl-5.8.9 --as perl-5.8.9-debug

Thoughts?

I'd be interested in something like profiles that could be set ahead of time and then invoked on install (with 'default' always being used if another isn't specified):

$ perlbrew profile set default -Doptimize=-O2 -Dman1dir=' ' -Dman3dir=' '
$ perlbrew install perl-5.8.9

Or for a particular profile:

$ perlbrew profile set debug -Doptimize=-O2 -Dman1dir=' ' -Dman3dir=' ' -Dusedebugging
$ perlbrew install --profile debug perl-5.8.9

Id like to +1 this feature request.

I always forget the recipe to say "use parallelism, use ccache, etc etc", which makes builds and tests vastly faster.

EG, during install I want -j 8, and i want -Dusedevel -Dcc=ccache\ gcc -Dld=gcc to be my standard build flags.

Thanks for the great tool, it makes hacking on core much easier. Especially testing code against old versions or different configs!
