+
+# 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.
