+# Usage:
+#
+# ./darcs-all [-q] [-s] [--nofib] [--testsuite] get [darcs get flags]
+#   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.
