34This script tests whether a Linux system is set up to build kernel modules,
35and if not prints a guess as to which distribution packages need to be
36installed to do so, and what commands to use. It uses the output of the
37"uname -r" command to guess the packages and searches for packaging tools
38by checking for packaging databases.
39
40For testing you can specify the output of "uname -r" which will be used
41instead of the real one and the package type, and optionally the expected
42output. --test without parameters will test a number of known inputs.'

44# General theory of operation (valid Nov 19 2016): we check whether this is an
45# rpm or dpkg system by checking for the respective non-empty database directory
46# (we assert that only one is present), and based on that we map uname -r output
47# to a kernel package name. Here is a textual description of known mappings
48# (not all of these are currently implemented) for both the general package name
49# and the version-specific package name. Keeping this here as it took some time
50# and pain to research.
