+# Posix detect program
+# (c) 2010 Andreas Rumpf
+
+# This program generates:
+# * A c program that prints a nim file containing constant variables holding the
+#   value of many C #define's, on the platform it's currently running at
+# * A nim file that contains the same contants, but as nim var:s that fetch the
+#   value of the constant using importc/header during the C compile phase.
+#
+# The first file allows nim to know the value of the constant at nim
+# compile time, but since the values differ across platform, isn't as portable.
+# The second one is more portable, and less semantically correct. It only works
+# when there's a backing C compiler available as well, preventing standalone
+# compilation.
