+#!/bin/bash
+
+# Simple little checker for individual libref manual sections
+#
+# usage: makesec.sh section
+#
+
+# This script builds the minimal file necessary to run a single section
+# through latex, does so, then converts the resulting dvi file to ps or pdf
+# and feeds the result into a viewer.  It's by no means foolproof, but seems
+# to work okay for me (knock wood).  It sure beats manually commenting out
+# most of the man lib.tex file and running everything manually.
+
+# It attempts to locate an appropriate dvi converter and viewer for the
+# selected output format.  It understands the following environment
+# variables:
+#
+#	PYSRC - refers to the root of your build tree (dir containing Doc)
+#	DVICVT - refers to a dvi converter like dvips or dvipdf
+#	VIEWER - refers to an appropriate viewer for the ps/pdf file
+#
+# Of the three, only PYSRC is currently required.  The other two can be set
+# to specify unusual tools which perform those tasks.
+
+# Known issues:
+#   - It would be nice if the script could determine PYSRC on its own.
+#   - Something about \seealso{}s blows the latex stack, so they need
+#     to be commented out for now.
