27 | * The .strings file format is simple: | |
28 | * | |
29 | * // comment | |
0837b7e8 | 30 | * "msgid" = "msgstr"; |
bc44d920 | 31 | * |

32 | * The GNU gettext .po format is also fairly simple: |
33 | * | |
34 | * #. comment | |
35 | * msgid "some text" | |
36 | * msgstr "localized text" | |
37 | * | |
38 | * The comment, msgid, and msgstr text can span multiple lines using the form: | |
39 | * | |
40 | * #. comment | |
41 | * #. more comments | |
42 | * msgid "" | |
43 | * "some long text" | |
44 | * msgstr "" | |
45 | * "localized text spanning " | |
46 | * "multiple lines" | |
47 | * | |
48 | * Both the msgid and msgstr strings use standard C quoting for special | |
49 | * characters like newline and the double quote character. | |
