JavaScript-Packer
-The README is used to introduce the module and provide instructions on
-how to install the module, any machine dependencies it may have (for
-example C compilers and installed libraries) and any other information
-that should be provided before the module is installed.
-
-A README file is required for CPAN modules since CPAN extracts the README
-file from a module distribution so that people browsing the archive
-can use it to get an idea of the module's uses. It is usually a good idea
-to provide version information here so that people can decide whether
-fixes for the module are worth downloading.
-
-
INSTALLATION
To install this module, run the following commands:
- perl Makefile.PL
- make
- make test
- make install
