DESCRIPTION
       shtool platform is a flexible Unix platform identification program.  It
       distinguishes a platform according to its hardware architecture and
       operating system. For both there is a class, product and technology
       identification. For each of those six identifications, there is a
       verbose, regular and concise version.

       This leads to eighteen (2x3x3) available identification strings for
       each platform, from which usually 2 are chosen in a particular
       situation.  This is done by assembling the platform identification
       string using a format string containing one or more identification
       constructs of the forms ""%[xx]"" (verbose), ""%{xx}"" (regular) and
       ""%<xx>"" (concise).

OPTIONS
       The following command line options are available.

       -F, --format format
           This option controls the output formatting of this program. It is a
           plain-text string with the ""%"xx" constructs which expand to the
           various platform information strings. ""%{"xx"}"" is the canonical
           regular version of the information. ""%["xx"]"" is the verbose
           version of the information. ""%<"xx">"" is the concise version of
           the information. In total, the following constructs are available
           for expansion:

            %[ac]    verbose hardware architecture class
            %{ac}    regular hardware architecture class
            %<ac>    concise hardware architecture class

            %[ap]    verbose hardware architecture product
            %{ap}    regular hardware architecture product
            %<ap>    concise hardware architecture product

            %[at]    verbose hardware architecture technology
            %{at}    regular hardware architecture technology
            %<at>    concise hardware architecture technology

            %[sc]    verbose operating system class
            %{sc}    regular operating system class
            %<sc>    concise operating system class

            %[sp]    verbose operating system product
            %{sp}    regular operating system product
            %<sp>    concise operating system product

            %[st]    verbose operating system technology

       -C, --conc string
           This option sets the word concatenation string for the platform
           information strings. By default it is ""/"". It is especially used
           to concatenate multiple parts in operating system name and version
           parts.

       -L, --lower
           This options enforces conversion of the output to all lower case.

       -U, --upper
           This options enforces conversion of the output to all upper case.

       -v, --verbose
           This option enforces verbose versions of all expansion constructs
           in format string of option -F. It is equal to specifying all
           expansion constructs as ""%["xx"]"".

       -c, --concise
           This option enforces concise versions of all expansion constructs
           in format string of option -F. It is equal to specifying all
           expansion constructs as ""%<"xx">"".

       -n, --no-newline
           This option omits the usual trailing newline character in the
           output.

       -t, --type type
           This option is a meta option which internally sets options -F, -S,
           -C, -L, -U, -v or -c according to TYPE. It can be used to easily
           specify various commonly known outputs. The following TYPEs are
           available:

           binary
               Binary Package Id (OpenPKG RPM).  This is equal to ""-F
               '%<ap"-%<sp>' -L -S '' -C '+'>" and results in outputs like
               ""ix86-freebsd4.9"" and ""ix86-debian3.0"".

           build
               Build-Time Checking (OpenPKG RPM).  This is equal to ""-F
               '%<at"-%<st>' -L -S '' -C '+'>" and results in outputs like
               ""i686-freebsd4.9"" and ""i586-linux2.4"".

           gnu GNU config.guess Style Id.  This is similar to build and is
               equal to ""-F '"%<at"-unknown-%<st>' -L -S '' -C '+'>" and
               results in outputs like ""i686-unknown-freebsd4.9"" and
               ""i586-unknown-linux2.4"".

           web HTTP Server Header Id.  This is equal to ""-F '"%<sp"-%<ac>' -S
               '/' -C '+'>" and results in outputs like ""FreeBSD/4.9-iX86""
               and ""Debian/3.0-iX86"".

           summary
               Human Readable Verbose Summary Information. This is equal to

           all-in-one
               All-In-One Full-Table Information. This just outputs really all
               2x2x3 identification strings as a table.

       -d, --debug
           This option enables some internal debugging messages.

       -V, --version
           This option outputs the version information of shtool platform
           only.

       -h, --help
           This option outputs the usage information of shtool platform only.

EXAMPLE
       The following real-life use cases are known:

       OpenPKG build-time decisions
            $ platform -c -L -S "" -C "+" -F "%at-%st"
            $ platform -c -L -S "" -C "+" -F "%ac-%sc"

       OpenPKG binary RPM packages
            $ platform -c -L -S "" -C "+" -F "%ap-%sp"

       README files
            $ platform -v -F "%sp (%ap)"
            $ platform -v -F "%sc (%ac)"

       Debugging
            $ platform --type=all-in-one

SUPPORT
       shtool platform currently knows the following particular Unix platforms
       in detail: FreeBSD, NetBSD, OpenBSD, Linux, Sun Solaris, SCO UnixWare,
       QNX Neutrino, SGI IRIX, HP HP-UX, HP Tru64, IBM AIX and Apple Mac OS X
       Darwin.

       All other Unix platforms are recognized through generic uname(1)
       information and so usually can be identified sufficiently, although the
       identification might be not as precise as possible.

HISTORY
       shtool platform was implemented in September 2003 by Ralf S.
       Engelschall for use in the OSSP and OpenPKG projects. It was prompted
       by the need in OpenPKG to have both product (for RPM filenames) and
       technology (for build-time decisions) identifiers for the Unix
       platforms, OpenPKG packages are maintained for. It was inspired by the
       GNU config.guess and the old GNU shtool guessos command.

       The major difference to GNU config.guess is that shtool platform does
       not use a vendor identification (cannot be determined most of the time
       and is not used at all in all projects I've ever seen) and is a lot
       more flexible (class, product and technology identifications combined
