/*
 * Very minimal (and stupid) implementation of gettext, with a fixed lookup
 * table.
 *
 * This library ONLY handles gettext(), and that only for the basic form (it
 * translates strings to other strings with no other modification, so %2$d
 * style constructs are not dealt with). The setlocale(), bindtextdomain(),
 * and textdomain() functions are ignored.
 *
 * To use this library, create a function that, given a language string,
 * returns a struct msg_table_s[] of msgid and msgstr pairs, with the end
 * of the table being marked by a NULL msgid. The po2table.sh script will do
 * this.
