parent proxy, if any, outside the squid.conf config file?

Basically I'd like to avoid having to edit the config file depending on
the network connected to.  Ideally I could specify it via environment
variable, but an option on the squid command line would do too.
  

You could run multiple squid.conf's and depending on which network 
you were
on, start squid up with the correct squid.conf file.  Check out the 
FAQ on
squid's command-line options.

The cache_peer directive doesn't appear to be one of the few that 
require a complete restart, so it may be possible to switch config 
files (or create by pluging values into a template), then do a reload.

Exactly: 2 (or more) squid.conf files, and a shell script somethign like 
the following:
(no guarantee that the script is error free, just typing it into 
thunderbird now...)

#!/bin/bash
SQUID_BIN=/opt/squid/sbin/squid
SQUID_CONF_DIR=/opt/squid/etc/
if [ ! -x ${SQUID_BIN} ]; then
       echo "Squid-Binary ${SQUID_BIN} is not executable!"
       exit 1
fi
case "$1" in
       work)
               cp ${SQUID_CONF_DIR}/squid.work.conf 
${SQUID_CONF_DIR}/squid.conf
               ${SQUID_BIN}-k reconfigure && echo "Squid sucessfully 
reconfigured fir ${1}" || echo "Squid could not be reconfigured for ${1}."
               ;;
       home)
               cp ${SQUID_CONF_DIR}/squid.home.conf 
${SQUID_CONF_DIR}/squid.conf
               ${SQUID_BIN}-k reconfigure && echo "Squid sucessfully 
reconfigured for ${1}" || echo "Squid could not be reconfigured for ${1}."
               ;;
       *)
               echo "Attempting to reconfigure squid for unknown 
location called ${1}..."
               if [ -f ${SQUID_CONF_DIR}/squid.${1}.conf ]; then
                  cp ${SQUID_CONF_DIR}/squid.${1}.conf 
${SQUID_CONF_DIR}/squid.conf  && echo "Wow, location ${1} really seems 
to exist."
               else
                   echo "${1} isn't a real place!"
                   echo "Usage: /usr/bin/squidswitch {work|home}"
               exit 1
               ;;
esac

exit 0
Obviously the first two options aren't really needed, but if you have 
good bash completion (i think) it might recognize the select case and 
complete the options.
