## Description

Are you lost ? Do you have trouble understanding this document ? In that case please read the overview provided by the Introduction to Parser Tools. This document is the entrypoint to the whole system the current package is a part of.

This package is an adjunct to pt::peg::to::tclparam, to make the use of this highly configurable package easier by providing a canned configuration. When applied this configuration causes the package pt::peg::to::tclparam to generate NX-based parser packages.

It is a supporting package in the Core Layer of Parser Tools.

## API

::pt::tclparam::configuration::nx def name pkg version cmdprefix

  The command applies the configuration provided by this package to the cmdprefix, causing the creation of NX-based parsers whose class is name, in package pkg with version.

  The use of a command prefix as API allows application of the configuration to not only pt::peg::to::tclparam (pt::peg::to::tclparam configure), but also export manager instances and PEG containers ($export configuration set and [$container exporter] configuration set respectively).

  Or anything other command prefix accepting two arguments, option and value.
