+
+# @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.
