Can you help me recover the original source code from my executable file?
The Support and Maintenance package for Perl Dev Kit does not include recovery of lost source code, and we do not have any special internal tools for reverse engineering wrapped code.
We recommend the use of distributed version control systems during development. Free services are available, and they provide many useful features in addition to ensuring that source code is not lost. Regular backups are still an alternative if you don't want to use version control.
