I just notice that using this version for LHA (lhasa) on debian:
```
Lhasa v0.3.1 command line LHA tool - Copyright (C) 2011,2012 Simon Howard usage: lha [-]{lvtxe[q{num}][finv]}[w=<dir>] archive_file [file...]
commands: options:
l,v List / Verbose List f Force overwrite (no prompt)
t Test file CRC in archive i Ignore directory path
x,e Extract from archive n Perform dry run
p Print to stdout from archive q{num} Quiet mode
v Verbose
w=<dir> Specify extract directory
```
the unpack command line at echocfg must be: lha -ew=%s %f
