 ## HTML Interface for the Perl Debugger
-   Any Perl script can be selected for debugging in an embedded HTML user interface. The debugger output is displayed together with the syntax highlighted source code of the debugged script and it's modules. Syntax highlighting is achieved using ```Syntax::Highlight::Engine::Kate``` CPAN module by Hans Jeuken and Gábor Szabó. Interaction with the built-in Perl debugger is an idea proposed by Valcho Nedelchev and provoked by the scarcity of graphical frontends for the built-in Perl debugger.
