13Packrat 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.

15For detailed information on the technique, please see Bryan Ford's web page at [[http://pdos.csail.mit.edu/~baford/packrat/|http://pdos.csail.mit.edu/~baford/packrat/]].

21== Repository
22
23This egg is hosted by the CHICKEN subversion server.  You can check it out with
24
25    $ svn co https://code.call-cc.org/svn/chicken-eggs/release/4/packrat
26
27You can use the {{anonymous}} user and empty password or authenticate
28with your own user in case you have one.
29
30Note that the URL points to the CHICKEN 4 version, as the code
31for CHICKEN 4 and CHICKEN 5 is the same (with some
32{{cond-expand}}s).  To avoid duplication of the `trunk' directory,
33the {{/release/4/packrat/trunk}} directory has been kept as the
34canonical development directory.  Releases are published to the
35CHICKEN version-specific directories
36accordingly ({{/release/4/packrat/tags}} and
37{{/release/5/packrat/tags}}).
