Installation instructions

pcidr runs in cgi or a mod_perl environment.

Following install instruction explains how to set
up pcidr in a cgi environment.

The example commands are good in a debian based operating
system. If you like to install pcidr on a different system
the example paths are different.

1. pcidr is based on some cpan modules. Use your
   cpan console to install following modules:
   
   HTML::Template
   HTML::Entities
   Net::CIDR
   
2. unpack the pcidr archive to a temporary folder:
   > cd /tmp/; tar xvzf pcidr.tar.gz

3. move the index.pl file to a subdirectory of your
   cgi-bin root directory:
   > mkdir /usr/lib/cgi-bin/pcidr
   > mv /tmp/pcidr/index.pl /usr/lib/cgi-bin/pcidr/
   
4. make sure that the index.pl file is executable:
   > chmod 755 /usr/lib/cgi-bin/pcidr/index.pl
   
5. move the pcidr modules to your perl include path:
   > mkdir /usr/local/lib/site_perl/PCIDR/
   > mv /tmp/pcidr/PCIDR/* /usr/local/lib/site_perl/PCIDR/
   
6. move the html part to a subdirectory of your web server
   root directory.
   (css, images, templates, example.html, pcidr_target.js)
   > mkdir /var/www/pcidr
   > mv /tmp/pcidr/* /var/www/pcidr/
   
7. check the path configuration in the constants.pm file:
   > vi /usr/local/lib/site_perl/PCIDR/constants.pm
   
   To keep up with this example change following values:
   
   PCIDR_TPLDIR   => '/var/www/pcidr/templates/'
   PCIDR_HTMLDIR  => '/pcidr/'
