windows - What is the recommended way to package perl scripts for CPAN (and CorporatePAN)? -

recently looked @ module on cpan comes script installed made me wonder. recommended way include script in package should end on public cpan , if there different recommendation packages released on in-house cpan server?

the script starts this:

#!/usr/bin/perl  eval 'exec /usr/bin/perl  -s $0 ${1+"$@"}'   if 0; # not running under shell 

two questions

do understand correctly eval part unnecessary? embedded cpan client during installation , different when installing on windows.

what recommended sh-bang line?

#!/usr/bin/env perl 

instead of above?

just use

#!/usr/bin/perl 

(or, optionally, whatever path perl on development machine.)

when module::build or makemaker installs script, change #! line match perl installing module. add "eval exec" lines, except under windows, create .bat file instead. (the cpan client has nothing this.)

if use

#!/usr/bin/env perl 

then installers won't realize that's perl script, , not modify #! line.
