+"Export custom language files to a target folder.
+Useful for uploading custom langstrings to AMOS or importing or syncing them to other moodle instances.
+
+Options:
+-l, --lang              Comma seperated language ids to export, default: all
+-c, --components        Comma seperated components to export, default: all
+-t, --target            Target to copy the zip files to, default: $CFG->tempdir/customlang
+-o, --overwrite         Overwrite existing files in the target folder.
+                            Note: If the target is not set, the files are always overwritten!
+-h, --help              Print out this help
+
+Examples:
+Export all custom language files to the default folder:
+\$ sudo -u www-data /usr/bin/php admin/tool/customlang/cli/export.php
+
+Export just the english files of moodle core and the activity 'quiz' in a subfolder in my home folder:
+\$ sudo -u www-data /usr/bin/php admin/tool/customlang/cli/export.php --lang='en' --components='moodle,quiz' --target='~/customdir'
