package require platform ?1.0.3?
The platform package provides several utility commands useful
for the identification of the architecture of a machine running Tcl.
Whilst Tcl provides the tcl_platform array for identifying the
current architecture (in particular, the platform and machine
elements) this is not always sufficient. This is because (on Unix
machines) tcl_platform reflects the values returned by the
uname command and these are not standardized across platforms and
architectures. In addition, on at least one platform (AIX) the
tcl_platform(machine) contains the CPU serial number.
Consequently, individual applications need to manipulate the values in
tcl_platform (along with the output of system specific
utilities) - which is both inconvenient for developers, and introduces
the potential for inconsistencies in identifying architectures and in
The platform package prevents such fragmentation - i.e., it
establishes a standard naming convention for architectures running Tcl
and makes it more convenient for developers to identify the current
architecture a Tcl program is running on.
