Download the swatch package, as shown in Section 2, “Packages required”. To install, simply issue the following commands:

perl Makefile.PL
make
make test
make install
make realclean
    

Swatch installs just like a CPAN module. If you are not familiar with this process then you may want to read about it by issuing the command:

man ExtUtils::MakeMaker
      

Use the perldoc command if your man cannot find the document.

If you see messages like these:

   
Warning: prerequisite Date::Calc 0 not found at (eval 1) line 219.
Warning: prerequisite Date::Parse 0 not found at (eval 1) line 219.
Warning: prerequisite File::Tail 0 not found at (eval 1) line 219.
Warning: prerequisite Time::HiRes 1.12 not found at (eval 1) line 219.
      

Then you need to install the CPAN module(s) that it doesn't find, before you can use swatch. You can find these modules at search.cpan.org. However, many operating systems may already provide perl rpm's so you should check with them first.

	Tip
	You can also use the command perl -MCPAN -e shell and get an interactive installer/shell, to install the perl modules. The shell is very simple and handles all dependancies. However, with any installer, manual intervention may be required to install the latest required package.
