-USAGE="[-a] [-r] [-m] [-t] [-n] [-b <newname>] <name>"
-LONG_USAGE="git-resurrect attempts to find traces of a branch tip
-called <name>, and tries to resurrect it.  Currently, the reflog is
-searched for checkout messages, and with -r also merge messages.  With
--m and -t, the history of all refs is scanned for Merge <name> into
-other/Merge <other> into <name> (respectively) commit subjects, which
-is rather slow but allows you to resurrect other people's topic
-branches."

-b,branch=            save branch as <newname> instead of <name>
-a,all                same as -l -r -m -t
-k,keep-going         full rev-list scan (instead of first match)
-l,reflog             scan reflog for checkouts (enabled by default)
-r,reflog-merges      scan for merges recorded in reflog
-m,merges             scan for merges into other branches (slow)
-t,merge-targets      scan for merges of other branches into <name>
-n,dry-run            don't recreate the branch"
