FOOD PREPARATION TIPS AND USEFUL INFORMATION: Install Perl CPAN Modules

For creating interesting scripts using perl, CPAN modules are essential. Say for web scraping WWW::Mechanize is an essential module. We can download and install cpan modules by logging into shell prompt as follows.:
1) In windows laptop, type cmd in search box
2) Try logging into cpan cshell as follows :
C:Userssh>perl -MCPAN -e install
It looks like you don't have a C compiler and make utility installed. Trying to install dmake and the MinGW gcc compiler using the Perl Package Manager.This may take a a few minutes...

Please use the `dmake` program to run commands from a Makefile!
Set up gcc environment - 3.4.5 (mingw-vista special r3)
After the installation is over, lets install a module say WWW::Mechanize for example. Here are the steps :
C:Userssh>perl -MCPAN -e shell
Set up gcc environment - 3.4.5 (mingw-vista special r3)
cpan shell -- CPAN exploration and modules installation (v1.9402)
Enter 'h' for help.
cpan> install WWW::Mechanize

WWW::Mechanize likes to have a lot of test modules for some of its tests.
The following are modules that would be nice to have, but not required.
Test::Pod
Test::Memory::Cycle
Test::Warn
Test::Taint

Looks good
