TXR is a new data munging language. TXR's special pattern language provides template-based matching of entire documents or large sections of documents. It also contains a language for functional and imperative programming. It is written in C and takes the form of a utility that is portable to Unix-like platforms and Windows.

Release Notes: This release adds some minor new functionality, fixes a broken floating-to-integer conversion function, and resolves a nagging syntactic issue.
Release Notes: This release adds some new syntactic sugar in the pattern language. On platforms which have sigaltstack, TXR programs can now catch and recover from a SIGSEGV caused by runaway recursion. A new prof operator measures the bytes allocated during the evaluation of an expression and the CPU time consumed. The API is now exposed to the trie data structure. Some new functions are added, and at least fourteen bugfixes.
