Subject: Commit langtool - a small perlscript to do some translation file
 manipulations. If you're modifying english.lang, stop for a moment to think
 if you could maybe use this script instead, and apply your change to all
 langfiles at once to avoid bothering our translators needlessly.

Also, check the diffs if you do use this script, because it might not be Bug Free[tm].

+Usage langtool --options langfile
+
+  For all actions, the modified langfile will be output on stdout. When doing
+  stuff to english.lang, you should almost always apply the same change to all
+  other languages to avoid bothering translators.
+
+  --deprecate --id ID_1,ID_2 --id ID_3 langfile
+
+    Deprecate a number of ids.
+    Example: langtool --id LANG_LEFT,LANG_RIGHT --LANG_BOTTOM english.lang
+
+  --changesource --id ID --target target --to string langfile
+    
+    Change the source text of a specific string specified by id and target. Use
+    this on all langfiles if you're changing a source in english.lang that
+    doesn't need attention from translators (case changes etc.).
+    Example:
+      langtool --changesource --id LANG_OK --target e200 --to "OK" english.lang
+
+  --changeid --from LANG_LFET --to LANG_LEFT langfile
+    
+    Change the name of an ID. THIS WILL BREAK BACKWARDS COMPATIBILITY. Use with
+    extreme caution.
+    Example: langtool --changeid --from LANG_OK --to LANG_YES english.lang
+
+  --changedesc --to string --id LANG_LEFT langfile
+
+    Change the desc for an ID.
+    Example: langtool --changedesc --to "New desc" --id LANG_OK english.lang
+
+  --changetarget --from target --to target --id ID1 langfile
+
+    Change the target for the specified id from one value to another
+    Example:
+      langtool --changetarget --from e200 --to e200,c200 --id LANG_ON dansk.lang
