ext extracts files from an archive using ASCII to EBCDIC character
translation and then goes back and identifies (by file suffix) those files 
in the archive that are binary files and re-extracts them without 
character translation.

Syntax:  ext archive

         where 'archive' is a tar (pax) archive file.

The default suffixes used to identify binary files are:

    ico ICO bmp BMP jpg JPG gif GIF,

but these can be changed by modifying the variable 'binary_suffixes' in
the script.

Details:

The script works by first extracting all files and performing character
translation on them from ASCII to EBCDIC.  The following pax command
is used (pax is the current standard for handling archives replacing
tar):

     pax -rvf archive -o to=IBM-1047,from=ISO8859-1

pax is then used to generate a list of files in the archive from which
all files with the defined binary suffixes are noted.  pax is then
invoked again to re-extract only the files with these suffixes without
using character translation:

     pax -rvf archive  binfile_1 binfile_2 ... binfile_n
