module for parsing command line arguments


Getopt::Declare provides facilities to parse command line options. It builds and runs a parser. The parser object can be saved and later run on different input. Key features are:

 * Automatic generation of error, usage and version information
 * Matching of parameter components may be constrained by regular expressions
 * Execution of embedded actions
 * Declarative specification of inter-parameter relationships
 * Selective or global case-insensitive matching of parameters
