53 * Parses portable object (PO) format.
54 *
55 * From http://www.gnu.org/software/gettext/manual/gettext.html#PO-Files
56 * we should be able to parse files having:
57 *
58 * white-space
59 * # translator-comments
60 * #. extracted-comments
61 * #: reference...
62 * #, flag...
63 * #| msgid previous-untranslated-string
64 * msgid untranslated-string
65 * msgstr translated-string
66 *
67 * extra or different lines are:
68 *
69 * #| msgctxt previous-context
70 * #| msgid previous-untranslated-string
71 * msgctxt context
72 *
73 * #| msgid previous-untranslated-string-singular
74 * #| msgid_plural previous-untranslated-string-plural
75 * msgid untranslated-string-singular
76 * msgid_plural untranslated-string-plural
77 * msgstr[0] translated-string-case-0
78 * ...
79 * msgstr[N] translated-string-case-n
80 *
81 * The definition states:
82 * - white-space and comments are optional.
83 * - msgid "" that an empty singleline defines a header.
84 *
85 * This parser sacrifices some features of the reference implementation the
86 * differences to that implementation are as follows.
87 * - No support for comments spanning multiple lines.
88 * - Translator and extracted comments are treated as being the same type.
89 * - Message IDs are allowed to have other encodings as just US-ASCII.
90 *
91 * Items with an empty id are ignored.
92 *
93 * @param resource $resource
94 *
