	php $file [OPTIONS]

	Manipulate translation files.

	-a, --action=ACTION
				select the action to perform. Available actions are add, delete,
				exist, format, ignore, and ignore_unmodified. This option is mandatory.
	-k, --key=KEY		select the key to work on.
	-v, --value=VAL		select the value to set.
	-l, --language=LANG	select the language to work on.
	-h, --help		display this help and exit.
	-r, --revert		revert the action (only for ignore action)
	-o, origin-language=LANG
				select the origin language (only for add language action)

EXAMPLES
Example 1:	add a language. It adds a new language by duplicating the referential.
	php $file -a add -l my_lang
	php $file -a add -l my_lang -o ref_lang

Example 2:	add a new key. It adds the key for all supported languages.
	php $file -a add -k my_key -v my_value

Example 3:	add a new value. It adds a new value for the selected key in the selected language.
	php $file -a add -k my_key -v my_value -l my_lang

Example 4:	delete a key. It deletes the selected key from all supported languages.
	php $file -a delete -k my_key

Example 5:	format i18n files.
	php $file -a format

Example 6:	ignore a key. Adds IGNORE comment to the key in the selected language, marking it as translated.
	php $file -a ignore -k my_key -l my_lang

Example 7:	revert ignore a key. Removes IGNORE comment from the key in the selected language.
	php $file -a ignore -r -k my_key -l my_lang

Example 8:	ignore all unmodified keys. Adds IGNORE comments to all unmodified keys in the selected language, marking them as translated.
	php $file -a ignore_unmodified -l my_lang

Example 9:	revert ignore on all unmodified keys. Removes IGNORE comments from all unmodified keys in the selected language.
		Warning: will also revert individually added unmodified keys.
	php $file -a ignore_unmodified -r -l my_lang

Example 10:	check if a key exist.
	php $file -a exist -k my_key\n\n
