+# This gets the GHC core repos, if they do not already exist.
+# -q says to be quite, and -s to be silent.
+# --nofib, --testsuite also get the nofib and testsuite repos respectively
+# The darcs get flag you are most likely to want is --complete. By
+# default we pass darcs the --partial flag.
+#
+# ./darcs-all [-q] [-s] cmd [darcs cmd flags]
+# This runs the darcs "cmd" command, with any flags you give, in all
+# of the repos you have checked out. e.g.
+# ./darcs-all pull
+# ./darcs-all -q send --dry-run
+# -q says to be quite, and -s to be silent.
