.SH MODULE
megaco_codec_transform \- Megaco message transformation utility\&.
.SH DESCRIPTION
.LP
This module implements a simple megaco message transformation utility\&.
.LP
\fINote\fR that this module is \fInot\fR included in the runtime part of the application\&.
.SH EXPORTS
.LP

tt() -> void()
.br
.RS
.LP
Transform messages using pretty text as base\&. Transform messages from pretty text encoding to compact, ber, per and erlang encoding\&.
.LP
This call is equivalent to the call: \fIt(pretty, [compact, ber, per, erlang])\fR

.LP
Called from the command line (shell) to transform all messages in a given codec dir to a given list of codec dirs\&. The dirs will \fInot\fR be created\&.
