Set MOD_PERLITE environment variables

[byrnereese]

For apparent symmetry with mod_perl, I wonder if it makes sense to seed the environment with info about mod_perlite. For example mod_perl apparently sets these variables:

MOD_PERL => mod_perl/2.0.4
MOD_PERL_API_VERSION => 2

Perhaps we should set:

MOD_PERLITE => mod_perlite/0.1

This is a bug logged in error. Mod_perlite was not being invoked as mod_perl was directed to process .pl files.

This is not a bug.
