       MBK_IN_FILTER - define the input filter


       MBK_IN_FILTER  set  the  input  filter  for  reading compressed Alliance files.  Filter is
       typically a string containing filename and options. This filter must read compressed  data
       flow  on it standard input and write non compressed data flow on it standard output. Files
       are taken in the first directory  where  they  are  found  according  to  the  environment
       variable  MBK_CATA_LIB.  If  a  file  compressed version and a file non compressed version
       exist booth in the same directory, the non compressed is opended, and a warning message is
       supllyed. To activate filters, variable MBK_FILTER_SFX must be set.


       Opening compressed files with gzip :
            setenv MBK_IN_FILTER "/asim/gnu/bin/gunzip -c"
            setenv MBK_FILTER_SFX ".gz"
