ENV SUMMARY="Platform for building and running Perl $PERL_VERSION applications" \
    DESCRIPTION="Perl $PERL_VERSION available as container is a base platform for \
building and running various Perl $PERL_VERSION applications and frameworks. \
Perl is a high-level programming language with roots in C, sed, awk and shell scripting. \
Perl is good at handling processes and files, and is especially good at handling text. \
Perl's hallmarks are practicality and efficiency. While it is used to do a lot of \
different things, Perl's most common applications are system administration utilities \
and web programming."
