xdg

Automatically uses environment variables, Windows Known Folders, and config files (e.g., user-dirs.dirs on Unix) to determine paths, with fallbacks for Unix, Windows, macOS, and Plan 9.

Strictly adheres to the XDG Base Directory Specification, including XDG user directories and non-standard extensions like XDG_BIN_HOME, as detailed in the README tables.

Provides helper functions like ConfigFile() and SearchConfigFile() to easily create and locate application files in appropriate directories, reducing boilerplate code.

Supports not only base XDG directories but also fonts, applications, and common user directories, ensuring broad filesystem compatibility.
