How much of Perl can be removed?
You might be interested in Microperl
and some other microperl link
From the readme:
microperl is supposed to be able a really minimal perl, even more
minimal than miniperl. No Configure is needed to build microperl,
on the other hand this means that interfaces between Perl and your
operating system are left very -- minimal.
All this is experimental. If you don't know what to do with microperl
you probably shouldn't. Do not report bugs in microperl; fix the bugs
If you are still reading this and you are itching to try out microperl
make -f Makefile.micro
Joost downtime n. The period during which a system
is error-free and immune from user input.
