A packrat parsing library
Packrat parsing is a memoizing, backtracking recursive-descent parsing technique that runs in time and space linear in the size of the input text. The technique was originally discovered by Alexander Birman in 1970 , and Bryan Ford took up the idea for his master's thesis in 2002.
For detailed information on the technique, please see Bryan Ford's web page at http://pdos.csail.mit.edu/~baford/packrat/.
A reference manual can be found here: packrat.pdf.
To use the packrat API, import the packrat module.
