#
## This module implements the basics for Linux distribution ("distro")
## detection and the OS's native package manager. Its primary purpose is to
## produce output for Nimble packages like::
##
## To complete the installation, run:
##
## sudo apt-get libblas-dev
## sudo apt-get libvoodoo
##
## The above output could be the result of a code snippet like:
##
## .. code-block:: nim
##
## if detectOs(Ubuntu):
## foreignDep "lbiblas-dev"
## foreignDep "libvoodoo"
##
