# A small script to rename all files in a directory semi-automatically.
# The main purpose is to smooth filenames in order for generatejplayer to work more nicely.
#
# WARNING: the files are renamed (ie. move in place) with no control : it might NOT work.

# Requires [smoothnameone.sh](https://bitbucket.org/lbesson/bin/src/master/smoothnameone.sh)
