Pegex is an Acmeist parser framework. It allows you to easily create parsers 
that will work equivalently in lots of programming languages! The inspiration 
for Pegex comes from the parsing engine upon which the postmodern programming 
language Perl 6 is based on. Pegex brings this beauty to the other justmodern 
languages that have a normal regular expression engine available.

Pegex gets it name by combining Parsing Expression Grammars (PEG), with 
Regular Expessions (Regex). That's actually what Pegex does.

PEG is the cool new way to elegantly specify recursive descent grammars. The 
Perl 6 language is defined in terms of a self modifying PEG language called 
Perl 6 Rules. Regexes are familiar to programmers of most modern programming 
languages. Pegex defines a simple PEG syntax, where all the terminals are 
regexes. This means that Pegex can be quite fast and powerful.

Pegex attempts to be the simplest way to define new (or old) Domain Specific 
Languages (DSLs) that need to be used in several programming languages and 
environments. Things like JSON, YAML, Markdown etc. It also great for writing 
parsers/compilers that only need to work in one language.
