look which and from where modules were included

I've just re-invented a wheel and discovered a way to say which modules uses given one, and from which location they come.
Quite simple and usefull (for me at least).

for Win32:

perl -Mvars -we "print join qq/\n/,map {qq/$_=>$INC{$_}/} sort keys %I
+NC"
[download]

for other systems (including Cygwin):

perl -Mvars -we 'print join qq/\n/,map {qq/$_=>$INC{$_}/} sort keys %I
+NC'
[download]

Sample output will be

Carp.pm=>D:/perl561/lib/Carp.pm
Exporter.pm=>D:/perl561/lib/Exporter.pm
strict.pm=>D:/perl561/lib/strict.pm
vars.pm=>D:/perl561/lib/vars.pm
warnings.pm=>D:/perl561/lib/warnings.pm
warnings/register.pm=>D:/perl561/lib/warnings/register.pm
[download]

If other module needed, specify, for example, other -M option

... and yes, it will be even shorter with `-l` option to shorten print statement... `perl -Mvars -lwe "print for map {qq/$_=>$INC{$_}/} sort keys %INC"` [download]	[reply] [d/l] [select]

svad++ This has just solved a little problem of mine finding where some troublesome modules where coming from on one system but not another, thanks. PerlMonks is the bees knees. Cheers, R. Pereant, qui ante nos nostra dixerunt!	[reply]
