Perl developers who work under Windows didn’t have possibility to install XS CPAN modules directly from CPAN. I used a command nmake from MS Visual Studio to do it. The project Strawberry Perl which is a part of Vanilla Perl Project changed this situation:
The purpose of the Strawberry Perl series is to provide a practical Win32 Perl environment for experienced Perl developers to experiment with and test the installation of various CPAN modules under Win32 conditions, and to provide a useful platform for doing real work.
In my mind Strawberry Perl appreciably lightens the life of Perl developers under Windows who don’t want to move to Linux.
