## simple bash to generate mummerplot of MATCH file
##
## Galaxy wrapper by Alex Bossers, CVI of Wageningen UR, Lelystad, NL
## alex_dot_bossers_at_wur_dot_nl
##
##
## needs a rename of the fixed name to something recognised by galaxy
## needs cleanout of temp files
##
## call is mummerplot $format  $in_match $out_file $cmd_extra
##             $0        $1         $2       $3       $4
##
## since mummerplot uses some deprecated syntax which can be fixed in the source
## we redirect STDERR to dev/null to circumvent errorstatus in galaxy
## io redirects 0=stdin 1=stdout 2=stderr to dev/null (or &-)

# adjust this for your machine
