In order to do that, it was necessary to make a bootstrap compiler that did the same thing. This way we could slowly build up the grammar, and make sure that the 2 compilers do the same thing. Parsing the Pegex language itself is not terribly hard, so this module just does it by hand. .PP Unless you are working on Pegex itself, you can ignore this module. .SH "SEE ALSO" .IX Header "SEE ALSO" .IP "\(bu" 4 Pegex::Compiler .SH "AUTHOR" .IX Header "AUTHOR" Ingy döt Net .SH "COPYRIGHT AND LICENSE" .IX Header "COPYRIGHT AND LICENSE" Copyright 2010\-2017.
