# Usage:
#
# ./darcs-all [-q] [-s] [-i] [-r repo] [--nofib] [--testsuite] get [darcs get flags]
# This gets the GHC core repos, if they do not already exist.
# ./darcs-all [-q] [-s] [-i] [-r repo]
# [--nofib] [--testsuite] [--checked-out] cmd [darcs flags]
#
# Applies the darcs command "cmd" to each repository in the tree.
#
# e.g.
# ./darcs-all -r http://darcs.haskell.org/ghc get
# To get any repos which do not exist in the local tree
#
# ./darcs-all -r ~/ghc-validate push
# To push all your repos to the ~/ghc-validate tree
#
# ./darcs-all pull -a
# To pull everything from the default repos
#
# ./darc-all push --dry-run
# To see what local patches you have relative to the main repos
#
# -q says to be quite, and -s to be silent.
#
# -i says to ignore darcs errors and move on to the next repository
#
# -r repo says to use repo as the location of package repositories
#
# --checked-out says that the remote repo is in checked-out layout, as
# opposed to the layout used for the main repo. By default a repo on
# the local filesystem is assumed to be checked-out, and repos accessed
# via HTTP or SSH are assumed to be in the main repo layout; use
# --checked-out to override the latter.
#
# --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] [-i] [-r repo] 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.
