Re: windows paths in shebang lines
There could a few good reasons to prefer Perl/ActiveState over Perl/cygwin, but then this would still be the wrong list. I hear that ActiveState has good support. BTW: I don't remember how I did that when I last tried to work with Perl/ActiveState (in WinNT times). There were several solutions and one of the simpler ones was to call the scripts like this perl script.pl On Tue, Jan 25, 2011 at 1:57 PM, Andrew DeFaria and...@defaria.com wrote: On 01/25/2011 08:50 AM, Rafael Kitover wrote: Now I just need to convince activestate to use proper shebang lines instead of #!/usr/bin/perl .

I know of a number of good reasons to favor Cygwin's Perl (and one would be not to have to deal with windows paths in the shebang lines!). but then this would still be the wrong list. I think promoting Cygwin, including Cygwin's Perl, is of good interest for even this list. I hear that ActiveState has good support. I don't know about that.
