# `pymcnp.outp` Subpackage

`pymcnp.outp` contains the OUTP parser. PyMCNP implements an object-oriented recursive
descent parser, approximating OUTP as the following context-free-grammar described in modified Backus-Naur form:

## AST Classes

PyMCNP represents OUTP non-terminals with AST classes and stores them in nested subpackages.
These AST class have methods for translating between PyMCNP and OUTP:

* `from_mcnp`. Parses OUTP source, checking for syntax and semantic errors.
* `to_mcnp`. Generates OUTP source from PyMCNP objects, reformatting.
