# 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 /var/dcc/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`
#		    '-T all' will compile but not install

#   -U		only fetch, unpack, and configure the tarball.  Do not compile
#		    or install the software.

#   -K		cron mode; configure, compile, and install only
#		    if the fetched version differs, and be silent when
#		    nothing is done

#   -k		not cron mode even if there is no controling tty

#   -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 errors from mkdir and so forth
