GF commandline client: clarify the meaning of the -langs parameter of gr and gt #64

Open GoogleCodeExporter opened 9 years ago

I find this confusing:

Words300> p -lang=Ace "no man that the dog bites knows John ." | gt
no trees found

Words300> p -lang=Ace "no man that the dog bites knows John ." | gt -lang=Ace
baseText (sText (s (vpS (noNP (relCN (cn_as_VarCN man_CN) (slashRS which_RP 
(theNP (cn_as_VarCN dog_CN)) (V2by_as_V2 bite_V2)))) (v2VP (V2by_as_V2 know_V2) 
(pnNP john_PN)))))

The omission of 'langs' seems to mean "do not generate trees which lack a 
linearization in at least one of the languages". It could be instead "do not 
generate trees which lack a linearization in all of the languages".

Also, 'langs' could allow meta values 'all' and 'some' in addition to the 
language list to make the default semantics clear.
