redo signfify options

2014-01-01 Thread Ted Unangst
I misinterpreted Theo's comments about the option letters before.

Revert to lowercase for most options, and change the verb option into
three distinct uppercase options, -G -S and -V.

Sorry Marc...

 The

 utility creates and verifies cryptographic signatures.
 The mode of operation is selected by the

 option.
 .Pp
 The options are as follows:
 .Bl -tag -width Ds
-.It Fl I Ar input
+.It Fl G
+Generate a new keypair.
+.It Fl S
+Sign the input file.
+.It Fl V
+Verify the input file and signature match.
+.It Fl i Ar input
 Input file to sign or verify.
-.It Fl N
+.It Fl n
 Do not ask for a passphrase during key generation.
 Otherwise,
 .Nm
 will prompt the user for a passphrase on the terminal.
-.It Fl O Ar output
+.It Fl o Ar output
 The signature file to create or verify.
 The default is

 .Ar verify
 to check a signature.
-.It Fl S Ar seckey
+.It Fl s Ar seckey
 Secret (private) key produced by

 Instead of
 signify -V -p pubkey -i input
 you want to be able to do
 signify -V -p pubkey  input ...
 
 e.g., at this point, input would not need to be an option, so that you
 can verify several files in one go.

we can do that too if we need batch verification, but I left it out
of this commit.

Well, at least make input not an option but an actual parameter.

Otherwise, you have a command with no parms.

And considering the command name, it makes little sense. As the name
says, that command is used to sign or verify a file. The *object* of that
command is the file. It's not an option !
