-
-	* install.sh:
-	Default installation behavior now changes dependent on $UID and
-	$SHELL. Root install will copy files into /usr/. Non-root installations
-	will install into current user's home directory. This behavior can be
-	overridden arguments with --global or --local.
-
-	Installation also now checks $SHELL to install the correct version. This
-	behavior can be overridden with --bash or --zsh.
+    - Man page and --help has been overhauled to provide better documentation
+    and usage scenarios.
+    - Installation scripts now act dependent on current
+    environmental settings.
+      If run as root, will do a global install. Installation script also
+      detects which version to install (bash or zsh) dependent on $SHELL.
+      Both of these behaviors can be overrode using --local/--global or
+      --bash/--zsh arguments.
+    - Uninstallation script added, will remove both global and local
+    installations but ignores database.
+    - Symlinks can be preserved as database entries, refer to man page for
+    more details.
+    - This change log added to better help package maintainers keep track of
+    changes between releases.
+    - Miscellaneous bug fixes.
