New Revision: 334181
URL: http://svnweb.freebsd.org/changeset/ports/334181

Log:
  New USES=dos2unix
  
  It is intended to replace USE_DOS2UNIX
  By default it convert all the source files
  Use:
  DOS2UNIX_FILES=	<a list of files>
  to convert files relative to ${WRKSRC} (globs allowed)
  DOS2UNIX_REGEX=	<a regex>
  To convert files matching the regex (using find -R -iregex)
  DOS2UNIX_GLOB= <a glob pattern>
  To convert files matching the glob pattern (using find -name)

Added:
  head/Mk/Uses/dos2unix.mk   (contents, props changed)

Added: head/Mk/Uses/dos2unix.mk
