Convert HWPX (Hanword) to 4 (Man Page)

HWPX (Hangul Word Processor XML) is an advanced document format used by Hanword, developed by Hancom. It serves as an XML-based alternative to the proprietary HWP format, enhancing interoperability and accessibility. Introduced to improve document structure and compatibility, HWPX enables easier data exchange, integration with various applications, and better support for modern document processing workflows. It is widely used in South Korea for official documents, offering structured content representation while maintaining the rich formatting capabilities of Hanword.

The 4 file extension refers to Unix Section 4 Manual Pages, which document special files and device drivers. These files, such as "mouse.4", describe how devices interact with the Unix operating system and are accessed using the "man" utility. Historically, these manual pages have been a fundamental part of Unix documentation, helping users understand and manage system devices.
