    address@hidden/var/typehack/ft2demos/bin% ./ftvalid -t ot /tmp/foo.c
    ./ftvalid -t ot /tmp/foo.c
    FT_OpenType_Validateis disabled. replace FreeType2 with otvalid-enabled 
version

      error = 0x0007


    address@hidden/var/typehack/ft2demos/bin% ./ftvalid -h
    ./ftvalid -h
    lt-ftvalid: invalid option -- h
