# wma converter 0.3.6 for Linux #
#################################

# Made by Peter Simon <simon.peter@linuxuser.hu>
# License: GNU GPL
#
# Needed programs:
#
# Getopt::Long - Perl Module
# MPlayer - http://www.mplayerhq.hu
# BladeEnc - http://bladeenc.mp3.no
# oggenc - http://www.vorbis.com
# mp3info - http://www.ibiblio.org/mp3info

# changelog:
# 0.1.0
# decoding all files to wav without any switches and encoders
# 0.2.0
# converting to mp3 or ogg with bitrate, delete options
# 0.2.1
# L.A.M.E. support for fanatics
# Default output filetype: ogg
# Some error warnings
# 0.3.0
# Reading the wma tags out and puting into the mp3 or the ogg tags. (What the MPlayer shows of those.)
# Default output bitrate: the original bitrate
# Simlink for the default encode mode (wma2ogg = ogg, wma2mp3 = mp3)
# 0.3.1
# Neglecting missing encoders if those are not in use.
# 0.3.2
# Using mp3info for the mp3 tags
# 0.3.3
# Convert more then one files in the start dir.
# 0.3.4-5
# Some bugfixes.
# 0.3.6
# Some bugfixes by Diego Biurrun

# Why BladeEnc?
# Eg.: The L.A.M.E.'s code isn't compatible for some hardwer-decoders. Makes noise and clashings.
# I never met this trouble using BladeEnc.
# That's it.
