Subject: add scripts/diffconfig.sh: a tool for making reduced .config files
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fsvn-archive%2Farchive.git;a=commitdiff_plain;h=b92f740db44f489d7348042ccb31d295c189dc07

add scripts/diffconfig.sh: a tool for making reduced .config files
these files contain only the target selection and options that differ from the default settings
this makes it much easier to review .config files
