-                * XXX - on Linux, are there any APIs to get the distribution
-                * name and version number?  I think some distributions have
-                * that.
-                *
-                * At least on Linux Standard Base-compliant distributions,
-                * there's an "lsb_release" command.  However:
-                *
-                *      http://forums.fedoraforum.org/showthread.php?t=220885
-                *
-                * seems to suggest that if you don't have the redhat-lsb
-                * package installed, you don't have lsb_release, and that
-                * /etc/fedora-release has the release information on
-                * Fedora.
-                *
-                *      http://linux.die.net/man/1/lsb_release
-                *
-                * suggests that there's an /etc/distrib-release file, but
-                * it doesn't indicate whether "distrib" is literally
-                * "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.
-                *
-                * At least on my Ubuntu 7 system, /etc/debian_version
-                * doesn't contain anything interesting (just some Debian
-                * codenames).
