# Change User Description Committed
#8 18619 Russell C. Jackson (Rusty) Updating main with current changes.
#7 15856 C. Thomas Tyler Replaced the big license comment block with a shortened
form referencing the LICENSE file included with the SDP
package, and also by the URL for the license file in
The Workshop.
#6 15777 C. Thomas Tyler No functional changes.

Style Policing only on bash scripts only.

Normalized indentation and line breaks, removed offending tabs, and general whitespace
usage.
#5 15609 C. Thomas Tyler Pushing SDP 2015.1.15607 (2015/09/02).
#4 13908 C. Thomas Tyler Pushing SDP 2015.1.13906.
#3 12171 Russell C. Jackson (Rusty) Merge in changes to remove the need for p4master_run.
#2 11459 mark_foundry Fixing the location of the upgrade.log.
Previously, it would try to write to /upgrade.log, which requires root permissions. So changed to use $LOGS which is what backupfunctions.sh uses, and is defined in p4vars. I've only tested upgrade.sh, as I don't have a pre-2013.3 server.
#1 10148 C. Thomas Tyler Promoted the Perforce Server Deployment Package to The Workshop.
