patch-pathlimit.py

"""
The reason for this script is to address the NINJA 260 character path limit in Windows.
The script creates a virtual drive that maps to the current directory.
This way, the path length is reduced to 2 characters (K: instead of the long path).
The K: drive can be removed by using `subst K: /d` or running the script again.
A system reboot will also remove the virtual drive.
