74?S: This variable contains the operating system name (e.g. sunos,
75?S: solaris, hpux, etc.). It can be useful later on for setting
76?S: defaults. Any spaces are replaced with underscores. It is set
77?S: to a null string if we can't figure it out.
78?S:.
79?S:osvers:
80?S: This variable contains the operating system version (e.g.
81?S: 4.1.3, 5.2, etc.). It is primarily used for helping select
82?S: an appropriate hints file, but might be useful elsewhere for
83?S: setting defaults. It is set to '' if we can't figure it out.
84?S: We try to be flexible about how much of the version number
85?S: to keep, e.g. if 4.1.1, 4.1.2, and 4.1.3 are essentially the
86?S: same for this package, hints files might just be os_4.0 or
87?S: os_4.1, etc., not keeping separate files for each little release.
88?S:.
89?C:OSNAME:
90?C: This symbol contains the name of the operating system, as determined
