#!/usr/bin/env bash
# This script is used to generate a gconv-modules file that takes into
# account only the gconv modules installed by Buildroot. It receives
# on its standard input the original complete gconv-modules file from
# the toolchain, and as arguments the list of gconv modules that were
# actually installed, and writes on its standard output the new
# gconv-modules file.
# The format of gconv-modules is precisely documented in the
# file itself. It consists of two different directives:
# module FROMSET TOSET FILENAME COST
# alias ALIAS REALNAME
# and that's what this script parses and generates.
#
# There are two kinds of 'module' directives:
# - the first defines conversion of a charset to/from INTERNAL representation
# - the second defines conversion of a charset to/from another charset
# we handle each with slightly different code, since the second never has
# associated aliases.
