=item 3.

The config.txt file contains sample settings please update each of 
setting with appropriate values:
 1. PATH: set to the values of the environment variable PATH
 2. PERL5LIB: set to the values of the environment variable PERL5LIB
 3. SC-cgi: specify the complete path to the SC-cgi directory placed under the web-server
 4. SC-htdocs: specify the complete path to the SC-htdocs directory placed under the web-server
 5. cgi: specify the name of the cgi directory for the web-server (eg: "cgi-bin" for apache2)

Several output files are created by the web-interface for which it 
requires read, write and execute permissions.

access till the SC-cgi/user_data and SC-htdocs directory. 
eg: all the directories in this path 
usr/local/apache2/cgi-bin/SC-cgi/user_data should have 
read-write-execute permissions.
