Start with + + man perl + +Note: You have to modify your man.conf file to search for manpages +in the /ade/lib/perl5/man/man3 directory, or the man pages for the +perl library will not be found. + +Note that dot (F<.>) is used as a package separator for documentation +for packages, and as usual, sometimes you need to give the section - C<3> +above - to avoid shadowing by the I<less(1) manpage>. + + +=head2 Perl HTML Documentation on AmigaOS + +If you have some WWW browser available, you can build B<HTML> docs. +Cd to directory with F<.pod> files, and do like this + + cd /ade/lib/perl5/pod + pod2html + +After this you can direct your browser the file F<perl.html> in this +directory, and go ahead with reading docs. + +Alternatively you may be able to get these docs prebuilt from C<CPAN>. + +=head2 Perl GNU Info Files on AmigaOS + +Users of C<Emacs> would appreciate it very much, especially with +C<CPerl> mode loaded.

Also, executing miniperl in backticks seems to +generate nothing: very probably related to the (v)fork problems. +B<Fixing the breakage requires someone quite familiar with the ixemul +library, and how one is supposed to run external commands in AmigaOS +without fork().> + +=head1 AUTHORS + +Norbert Pueschel, pueschel@imsdd.meb.uni-bonn.de +Jan-Erik Karlsson, trg@privat.utfors.se + +=head1 SEE ALSO + +perl(1). + +=cut |
