# System-supplied tools for the Linux operating system.
#
# Yet all ye who enter be warned: various Linux distributions
# place binaries in a myriad of different paths and have a myriad
# of different userspaces.  No assumptions can be made, so this
# is best-effort.  Some distributions do not follow a remotely
# Unix-like file hierarchy.
#
# This file still assumes (until it is proven wrong) that some
# tools are provided by GNU.
