t_coffee -clean :: inconsistency

[EricDeveaud]

Hello,

while looking at t_coffee -help I noticed an inconstency -clean is declared twice with some inconsintency
see:

t_coffee -help -clean

PARAMETER   : -clean
USAGE       : Will delete cached data and exit: all, cache, lock, tmp. It is possible to specify a list: cache_lock_tmp
MAX_N_VALUES: 1
DEFAULT     : no OR all (when flag set)
RANGE       : [any]...[]
TYPE        : S

PARAMETER   : -clean
USAGE       : Deprecated
MAX_N_VALUES: 1
DEFAULT     : no OR shadow (when flag set)
RANGE       : [any]...[]
TYPE        : S

I did not check the code to track down the problem

regards

Eric
