-# Usage:
-#
-# ./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
-#
-# -------------- Flags -------------------
-# -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.
-#
-# ------------ Which repos to use -------------
-# darcs-all uses the following algorithm to decide which remote repos to use
-#
-# It always computes the remote repos from a single base, $repo_base
-# How is $repo_base set?
-# If you say "-r repo", then that's $repo_base
-# othewise $repo_base is set thus:
-# look in _darcs/prefs/defaultrepo,
-# and remove the trailing 'ghc'
-#
-# Then darcs-all iterates over the package found in the file
-# ./packages, which has entries like:
-# libraries/array packages/array darcs
-# or, in general
-# <local-path> <remote-path> <vcs>
-#
-# If $repo_base looks like a local filesystem path, or if you give
-# the --checked-out flag, darcs-all works on repos of form
-# $repo_base/<local-path>
-# otherwise darcs-all works on repos of form
-# $repo_base/<remote-path>
-# This logic lets you say
-# both darcs-all -r http://darcs.haskell.org/ghc-6.12 pull
-# and darcs-all -r ../HEAD pull
-# The latter is called a "checked-out tree".
-
-# NB: darcs-all *ignores* the defaultrepo of all repos other than the
-# root one. So the remote repos must be laid out in one of the two
-# formats given by <local-path> and <remote-path> in the file 'packages'.
