Perl∷Critic.

The article demonstrates the use of Perl::Critic, a system that analyzes Perl source code to search for deviations from code standards. In a given example, Perl Critic is used do detect errors in a code that reads connection information from a comma-separated values (CSV) file. The code uses a connect ( ) method which overrides DBI connect ( ) and does a look-up in a CSV file to get the authentication information and other options.
