+#!/bin/sh
+#
+# This script builds and installs binutils, gcc and newlib in the order
+# necessary for the whole thing to work.  The present version is based
+# on OsmocomBB's gnu-arm-build.2.sh script, which is in turn based on
+# yet another source.  The present version has been concocted by
+# Spacefalcon the Outlaw for use in the FreeCalypso project.
+#
+# This script needs to be invoked with two arguments:
+#
+# $1: the path to the directory containing the upstream binutils, gcc
+#     and newlib source tarballs;
+#
+# $2: the path to the directory where the built toolchain should be
+#     installed.
+#
+# Note that there isn't a single install step at the end, instead this
+# script will build and install one component, then proceed to build the
+# next component which depends on the previous one, etc.  For this reason
+# you should create a dedicated install directory that is writable by your
+# regular (non-root) uid, then run this script to populate that directory
+# with the toolchain.
