# @BLURB: convert files from DOS CRLF to UNIX LF line endings

# @FUNCTION: edos2unix
# @USAGE: <file> [more files ...]
# @DESCRIPTION:
# A handy replacement for dos2unix, recode, fixdos, etc...  This allows
# you to remove all of these text utilities from DEPEND variables
# because this is a script based solution.  Just give it a list of files
# to convert and they will all be changed from the DOS CRLF format to
# the UNIX LF format.
