-----------------------------------+----------------------------------------
 There are number of problems with the epubcheck wrapper script provided
 with this port:

  * creates temporary files without using/checking TMPDIR or TEMP
  * merges output of STDOUT and STDERR (2>&1)
  * looses the exit code returned by the epubcheck application itself, and
 instead parses the combined output
  * looses the ability to pass files with spaces in the name (uses $@
 instead of "$@")

 I'm attaching a patch containing a simplified script that corrects these
 issues.
