+## Overview
+
+# Heuristics to assemble a platform identifier from publicly available
+# information. The identifier describes the platform of the currently
+# running tcl shell. This is a mixture of the runtime environment and
+# of build-time properties of the executable itself.
+#
+# Examples:
+# <1> A tcl shell executing on a x86_64 processor, but having a
+#   wordsize of 4 was compiled for the x86 environment, i.e. 32
+#   bit, and loaded packages have to match that, and not the
+#   actual cpu.
+#
+# <2> The hp/solaris 32/64 bit builds of the core cannot be
+#   distinguished by looking at tcl_platform. As packages have to
+#   match the 32/64 information we have to look in more places. In
+#   this case we inspect the executable itself (magic numbers,
+#   i.e. fileutil::magic::filetype).
+#
+# The basic information used comes out of the 'os' and 'machine'
+# entries of the 'tcl_platform' array. A number of general and
+# os/machine specific transformation are applied to get a canonical
+# result.
+#
+# General
+# Only the first element of 'os' is used - we don't care whether we
+# are on "Windows NT" or "Windows XP" or whatever.
+#
+# Machine specific
+# % arm*   -> arm
+# % sun4*  -> sparc
+# % intel  -> ix86
+# % i*86*  -> ix86
+# % Power* -> powerpc
+# % x86_64 + wordSize 4 => x86 code
+#
+# OS specific
+# % AIX are always powerpc machines
+# % HP-UX 9000/800 etc means parisc
+# % linux has to take glibc version into account
+# % sunos -> solaris, and keep version number
+#
+# NOTE: A platform like linux glibc 2.3, which can use glibc 2.2 stuff
+# has to provide all possible allowed platform identifiers when
+# searching search. Ditto a solaris 2.8 platform can use solaris 2.6
+# packages. Etc. This is handled by the other procedure, see below.
