#           Its handy to set this value to false, 
#           to test new versions of releng.wtpbuilder
#           If set to false, local edits to wtpbuilder files
#           are not over written each time a 
#           build starts. 
#           Normally always 'true' for "production" builds, 
#           in which case the version of releng.wtpbuilder 
#           specificed in releng/build.cfg is used for the build.
