App::perlvars - CLI tool to detect unused variables in Perl modules
You probably don't want to use this class directly. See perlvars for documentation on how to use the command line interface.
The path to a file containing a list of variables to ignore on a per-package basis. The pattern is Module::Name = $variable or Module::Name = qr/some regex/. For example:
Module::Name = $variable
Module::Name = qr/some regex/
Local::Unused = $unused
Local::Unused = $one
Local::Unused = $two
Local::Unused = qr/^\$.*hree$/
Path to a file which will be validated. Returns an exit code, an error message and a list of unused variables.
