/**
 * @brief Main entry point for the musredit application.
 *
 * @details musredit is a simple editor-based interface to the musrfit programs,
 * providing a graphical environment for creating, editing, and managing
 * muon spin rotation (μSR) fit parameter files.
 *
 * The application is built using the Qt framework and provides the following features:
 * - Multi-document editing of msr (muon spin rotation) parameter files
 * - Syntax highlighting for msr file format
 * - Integration with musrfit analysis tools (musrfit, musrview, msr2data, etc.)
 * - Recent file tracking and session management
 *
 * @par Command Line Options:
 * - No arguments: Launch the editor with an empty document
 * - \<msr-files\>: Open the specified msr file(s) for editing
 * - \c -h, \c --help: Display usage information and exit
 * - \c -v, \c --version: Display version/git revision information and exit
 *
 * @par License:
 * musredit is free software licensed under GPL v2 or later.
 * See http://www.gnu.org/licenses for details.
 *
 * @param argc Number of command-line arguments
 * @param argv Array of command-line argument strings
 *
 * @return 0 on successful execution or when displaying help/version,
 *         or the Qt application exit code from QApplication::exec()
 *
 * @see PTextEdit The main editor window class
 * @see https://qt.io Qt framework documentation
