# 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
+#
+# ------------ 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'.
+
+# -------------- 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.
#
-# ./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.
