+# This is a handcrafted wrapper script which runs the actual (autoconf)
+# 'configure' scripts in different parts of OTP.
+#
+# The true (autoconf) configure scripts are run in parallel unless
+# --disable-parallel-configure is passed as argument to this script.
+#
+# The config cache feature is disabled since it mostly causes problems
+# and especially when executing multiple configure scripts in parallel.
+# On windows a static cache for each configure is used since it
+# otherwise takes forever to run configure...
