LEF/DEF suffixes can be configured 

The way to specify them is through the following
environment variables:

$KLAYOUT_LEF_FORMAT - LEF suffixes (default: "*.lef *.LEF *.lef.gz *.LEF.gz")
$KLAYOUT_DEF_FORMAT - DEF suffixes (default: "*.def *.DEF *.def.gz *.DEF.gz")

The string is a space-separated list of simple
match pattern. Only "*.xyz"-style pattern are allowed
currently.
