+# pgettext and buddies
+
+Default installation of `gettext` in php lacks support for `pgettext` et al.
+This php script adds support for those, as well as an `gettext_noop` wrapper.
+
+For this to work when extracting strings using `xgettext`, many keyword parameters needs to be filed,
+A wrapper script called `php-xgettext` might be used to simplify this.
+
+Following functions are exported:
+
+* `pgettext($msg_ctxt, $msgid)`
+* `dpgettext($domain, $msg_ctxt, $msgid)`
+* `dcpgettext($domain, $msg_ctxt, $msgid, $category)`
+* `npgettext($msg_ctxt, $msgid, $msgid_plural, $n)`
+* `dnpgettext($domain, $msg_ctxt, $msgid, $msgid_plural, $n)`
+* `dcnpgettext($domain, $msg_ctxt, $msgid, $msgid_plural, $n, $category)`
+* `gettext_noop($msgid)`
