* "distrib" or is the name for the distribution, and
* also speaks of an /etc/debian_version file.
*
* "lsb_release" apparently parses /etc/lsb-release, which
* has shell-style assignments, assigning to, among other
* values, DISTRIB_ID (distributor/distribution name),
* DISTRIB_RELEASE (release number of the distribution),
* DISTRIB_DESCRIPTION (*might* be name followed by version,
* but the manpage for lsb_release seems to indicate that's
* not guaranteed), and DISTRIB_CODENAME (code name, e.g.
* "licentious" for the Ubuntu Licentious Lemur release).
* the lsb_release man page also speaks of the distrib-release
* file, but Debian doesn't have one, and Ubuntu 7's
* lsb_release command doesn't look for one.
*
* I've seen references to /etc/redhat-release as well.
