System Identification
=====================

 - primitive: uname
     Returns an object with some information about the computer system
     the program is running on.

The following procedures accept an object as returned by `uname' and
return a selected component.

`utsname:sysname'
     The name of the operating system.

`utsname:nodename'
     The network name of the computer.

`utsname:release'
     The current release level of the operating system implementation.

`utsname:version'
     The current version level within the release of the operating
     system.

`utsname:machine'
     A description of the hardware.

 - primitive: software-type
     Return a symbol describing the current platform's operating system.
     This may be one of AIX, VMS, UNIX, COHERENT, WINDOWS, MS-DOS, OS/2,
     THINKC, AMIGA, ATARIST, MACH, or ACORN.

     Note that most varieties of Unix are considered to be simply
     "UNIX".  That is because when a program depends on features that
     are not present on every operating system, it is usually better to
     test for the presence or absence of that specific feature.  The
     return value of `software-type' should only be used for this
     purpose when there is no other easy or unambiguous way of
     detecting such features.
