+#!/bin/bash
+#
+# Save/restore your .git/config files in a central place.
+#
+# When called as "git-config-save" or "git config-save",
+# this scripts traverses a folder looking for all .git/config files
+# and makes backups at ~/.config/gitconfigs.
+#
+# When called as "git-config-restore" or "git config-restore"
+# it does the reverse operation: restores all .git/config
+# files, replacing the current repository .git/config's by the one
+# available from ~/.config/gitconfigs.
+#
+# Use cases:
+#
+# - You work with the repositories in multiple machines and is
+# looking for a way to sync not just the content but also the
+# same repository configuration (user name, remotes, etc).
+#
+# - You want to delete working copies of repositories but want
+# to keep each repository configuration for future use. In that
+# case all you have to do is to clone the repository again and
+# run this command inside your working copy.
+#
+# You may want to put in a schedule job to process all your stuff regularly.
+#
+# Storage format:
+#
+# - Use ~/.config/gitconfigs/ as base
+# - Repository identifier is determined by the first commit ID
+# (not repo URL or any other volatile information). So this
+# script may fail if you're doing improbable stuff like rebasing
+# your repo and removing the initial commit.
+#
+# How it saves an item:
+#
+# - Find all git configurations
+# - Make a backup at $BASE/$ID/config.$DATE if config differs
+# - Save the config at $BASE/ID
+#
+# How it restore an item:
+#
+# - Copy each config from $BASE/ID, if available and if it differs
+# - Restore always save a timestamped copy at .git/config.$DATE
+
