+/* Compiler for language definition files.
+ *
+ * (C) 2003-2008 Anope Team
+ * Contact us at info@anope.org
+ *
+ * Please read COPYING and README for further details.
+ *
+ * Based on the original code of Epona by Lara.
+ * Based on the original code of Services by Andy Church.
+ * 
+ * $Id$

+
+/*
+ * A language definition file contains all strings which Services sends to
+ * users in a particular language.  A language file may contain comments
+ * (lines beginning with "#") and blank lines.  All other lines must adhere
+ * to the following format:
+ *
+ * Each string definition begins with the C name of a message (as defined
+ * in the file "index"--see below).  This must be alone on a line, preceded
+ * and followed by no blank space.  Following this line are zero or more
+ * lines of text; each line of text must begin with exactly one tab
+ * character, which is discarded.  Newlines are retained in the strings,
+ * except the last newline in the text, which is discarded.  A message with
+ * no text is replaced by a null pointer in the array (not an empty
+ * string).
+ *
+ * All messages in the program are listed, one per line, in the "index"
+ * file.  No comments or blank lines are permitted in that file.  The index
+ * file can be generated from a language file with a command like:
+ *	grep '^[A-Z]' en_us.l >index
+ *
+ * This program takes one parameter, the name of the language file.  It
+ * generates a compiled language file whose name is created by removing any
+ * extension on the source file on the input filename.
+ *
+ * You may also pass a "-w" option to print warnings for missing strings.
+ *
+ * This program isn't very flexible, because it doesn't need to be, but
+ * anyone who wants to try making it more flexible is welcome to.
