Sometimes when you are developing software there can several module code
repositories involved. This module lets you specify which repositories you
want to load modules from, and formats them into a PERL5LIB environment
variable format.

Devel::Local takes a list of Perl module repositories that you specify in
your current directory or your home directory. It adds the absolute paths
of the lib/ subdirectories to the current value of PERL5LIB. It can also
add the bin/ subdirectories to your PATH environment variable. It prints
the new value to STDOUT and then exits.

NOTE: If Devel::Local runs into problems, it will warn about them, but
still print your environment variable.
