Hello First of all: Thanx for your excellent effort on all this. But: Where do I find information about, how to make the core module distribution. It seems to be a rule, that the module is contained in a gzip. And it seems to be standard, that installation involves execution of the commands perl Makefile.PL make make test (see http://18.85.40.23/INSTALL.html). But what are the rules to make the new module following this installation procedure? Is there some Perl-build-in technology helping on this? I would like you to be very specific about this. Have I missed something? Or aren't there any rules at all? I would also like some explanation about how all this is related to using / writing external code (C, etc.) with Perl modules and distributions. If all this is proberly dealt with on CPAN (I haven't found anything) - why don't you give an explicit link to it? Best regards Frank Norman, Denmark Tel. +45 4334 5205
