+# Fetch, build, install, and start a new version of the DCC just
+#   as it was configured last time.
+
+# This script should only be used after the DCC has been correctly configured.
+
+# If this script fails in its efforts to use wget, curl, fetch, or ftp
+#   to download a new tarball, then manually download a tarball to
+#   build subdirectory in the DCC home directory, probably @prefix@/build.
+#   This script unpacks the newest DCC tarball it finds in that directory,
+#   which will probably be the manually download file.
+
+
+# This script should usually not be used if large configuration changes are
+#   needed.  Instead use `./configure ...; make install` as usual.  That will
+#   create a new version of this script with the ./configure settings captured.
+#   However, -eENV=VAL and -cCONF=VAL can be used to tweak an installation,
+#	as in `updatedcc -c--with-uid=dcc` `updatedcc -c--without-uid`
+#	or `updatedcc -e DBGFLAGS=-g`
+
+#   -e ENV=VAL	set environment variable ENV to VAL before running ./configure
+
+#   -c CONF=VAL	add "CONF=VAL" to the end of the settings given ./configure
+
+#   -s base-URL	fetch the tarball using base-URL instead of the default.
+#		    The name of the tarball is appended to base-URL.
+
+#   -V x.y.z	try to fetch version x.y.z of the tarball instead of the
+#		    the most recent verison
+
+#   -C pfile	fetch theDCC source using parameters in pfile
+
+#   -T tgt	target instead of "install" for `make`
+
+#   -U		only fetch, unpack, and configure the tarball.  Do not compile
+#		    or install the software.
+
+#   -K		cron (kron) mode; configure, compile, and install only
+#		    if the fetched version differs, and be silent when
+#		    nothing is done
+
+#   -x		debug
+#   -v		verbose
+
+
+# This script should be run as root, but can be run as the non-root
+# user that runs dccm and dccd.  If not run as root, it cannot install
+# man pages or user commands including cdcc and dccproc.
+
+# The following environment variables are set by this script to their values
+#   when ./configure or this script was last run:
+#   Unsetting variables that are not set often yields a non-zero command status
+#   so do this before watching for error from mkdir and so forth
