Convert CWK to 5 (Man Page)

The CWK file extension stands for ClarisWorks Document, specifically used for word processing documents within ClarisWorks (later AppleWorks). Apple rebranded ClarisWorks to AppleWorks after acquiring Claris in 1998 and discontinued it in 2004. These CWK files have since been largely replaced by formats like PAGES in Apple's iWork suite. Opening CWK word processing files now requires older versions of Apple's Pages.

The 5 file extension refers to Unix Section 5 Manual Pages, which document file formats and conventions used in Unix-like operating systems. These manual pages, accessible via the "man" utility, provide detailed information on system-level file formats, such as "deb.5" for the DEB file format. Historically, Section 5 has been a crucial resource for system administrators and developers to understand and manage various file formats and system conventions in Unix environments.
