./manual gives users a text-based interactive interface to local or
remote tokens.  This is extremely useful for manually testing the
token server and setting up deadlock scenarios.

Run it as follows

% ./manual -u
./manual:
[-h <remote host>]
[-p <remote port>]
[-i ignore deadlock]
[-d debug]

./manual gives you the following prompt.
<tid> <token> <type> <operation>

<tid>  This is the client id of the current operation.  This is set
       manually by ./manual for every operation.  Be careful when
       using multiple <tid>'s during a remote session (see BUGS
       below).

<token> This is the name of the token for the operation.

<type> This is the type of the token.  This can be:
       M - Corresponds to a Mutex lock.
       R - Corresponds to Readers/Writer lock.
       W - Corresponds to Readers/Writer lock.
       Obviously, a single <token> can be M or it can R and/or W.  If
       you perform and operation like this "tid1 tokenA M A" then
       don't do this "tid1 tokenA R A".  This doesn't make sense.

<operation> This is the operation to perform on the
       <tid>-<token>-<type> proxy.  These include:
       A - acquire.
       N - renew.
       R - release.
       T - tryacquire.

BUGS!!!!

When performing remote tests, be careful when using a single running
./manual to impersonate two <tid>'s.  The Token Server client
connection policy is currently, one per thread.  The Token Server
assumes that the same <tid> is always on the other end of a
connection.  If you do something like the following, you will break
it:

lambada:Tokens/manual> ./manual -h tango -p 20202
<tid> <token> <type> <operation>
tid1 tokenA M A
ACE_TSS_Connection new connection
(1) acquired tokenA remotely.
Succeeded.
<tid> <token> <type> <operation>
tid2 tokenA M A
(1) acquired tokenA remotely.   <------  This is remote BADness!!!
Succeeded.
Violated invariant.             <------  Locally detected badness.
<tid> <token> <type> <operation>


Notice that the local side discovered that this was incorrect.
However, the Token Server thinks it was a recursive acquisition for
tid1.  Keep in mind that this is not a problem with the Token library.
It is just a problem with how this primitive ./manual application maps
STDIN to the ACE Token API.
