class TProof: public TNamed, public TQObject

 Create a PROOF environment. Starting PROOF involves either connecting
 to a master server, which in turn will start a set of slave servers, or
 directly starting as master server (if master = ""). Masterurl is of
 the form: [proof[s]://]host[:port]. Conffile is the name of the config
 file describing the remote PROOF cluster (this argument alows you to
 describe different cluster configurations).
 The default is proof.conf. Confdir is the directory where the config
 file and other PROOF related files are (like motd and noproof files).
 Loglevel is the log level (default = 1). User specified custom config
 files will be first looked for in $HOME/.conffile.

 Protected constructor to be used by classes deriving from TProof
 (they have to call Init themselves and override StartSlaves
 appropriately).

 This constructor simply closes any previous gProof and sets gProof
 to this instance.

 Clean up PROOF environment.

 Start the PROOF environment. Starting PROOF involves either connecting
 to a master server, which in turn will start a set of slave servers, or
 directly starting as master server (if master = ""). For a description
 of the arguments see the TProof ctor. Returns the number of started
 master or slave servers, returns 0 in case of error, in which case
 fValid remains false.

 Set manager and schedule its destruction after this for clean
 operations.

 Start up PROOF slaves.

 Close all open slave servers.
 Client can decide to shutdown the remote session by passing option is 'S'
 or 's'. Default for clients is detach, if supported. Masters always
 shutdown the remote counterpart.

 Create a new TSlave of type TSlave::kSlave.
 Note: creation of TSlave is private with TProof as a friend.
 Derived classes must use this function to create slaves.

 Derived classes must use this function to create slaves.

 Add to the fUniqueSlave list the active slaves that have a unique
 (user) file system image. This information is used to transfer files
 only once to nodes that share a file system (an image). Submasters
 which are not in fUniqueSlaves are put in the fNonUniqueMasters
 list. That list is used to trigger the transferring of files to
 the submaster's unique slaves without the need to transfer the file
 to the submaster.

 Return number of slaves as described in the config file.

 Return number of active slaves, i.e. slaves that are valid and in
 the current computing group.

 unique different user files system.

 file, but refused to startup or that died during the PROOF session.

                   server, i.e. even those processed by other sessions
           "L"     show only information about queries locally available
                   i.e. already retrieved. If "L" is specified, "A" is
                   ignored.
           "F"     show all details available about queries
           "H"     print help menu

 succes.

 Send command to be executed on the PROOF master and/or slaves.

 Check if a file needs to be send to the slave. Use the following
 algorithm:
   - check if file appears in file map
     - if yes, get file's modtime and check against time in map,
       if modtime not same get md5 and compare against md5 in map,
       if not same return kTRUE.
     - if no, get file's md5 and modtime and store in file map, ask
       slave if file exists with specific md5, if yes return kFALSE,
       if no return kTRUE.
 Returns kTRUE in case file needs to be send, returns kFALSE in case
 file is already on remote node.

       kBinary (0x1)      if set true binary file transfer is used
       kForce  (0x2)      if not set an attempt is done to find out
                          whether the file really needs to be downloaded
                          (a valid copy may already exist in the cache
                          from a previous run); the bit is set by
                          UploadPackage, since the check is done elsewhere.
       kForward (0x4)     if set, ask server to forward the file to slave
                          or submaster (meaningless for slave servers).

 was sent to, -1 in case of error.

 was sent to. Returns -1 in case of error.

 Set server logging level.

 Switch ON/OFF the real-time logging facility. When this option is
 ON, log messages from processing are sent back as they come, instead of
 being sent back at the end in one go. This may help debugging or monitoring
 in some cases, but, depending on the amount of log, it may have significant
 consequencies on the load over the network, so it must be used with care.

 selection is done (if nodes is less than the available nodes).
 Returns the number of parallel slaves. Returns -1 in case of error.

 Tell PROOF how many slaves to use in parallel. Returns the number of
 parallel slaves. Returns -1 in case of error.

 If random is TRUE, and nodes is less than the number of available workers,
 a random selection is done.
 Returns -1 in case of error.

 script if it exists on the client.
 Returns 0 in case of success and -1 in case of error.

 Returns 0 in case of success and -1 in case of error.

 Upload a PROOF archive (PAR file). A PAR file is a compressed
 tar file with one special additional directory, PROOF-INF
 (blatantly copied from Java's jar format). It must have the extension
 .par. A PAR file can be directly a binary or a source with a build
 procedure. In the PROOF-INF directory there can be a build script:
 BUILD.sh to be called to build the package, in case of a binary PAR
 file don't specify a build script or make it a no-op. Then there is
 SETUP.C which sets the right environment variables to use the package,
 like LD_LIBRARY_PATH, etc.
 The 'opt' allows to specify whether the .PAR should be just unpacked
 in the existing dir (opt = kUntar, default) or a remove of the existing
 directory should be executed (opt = kRemoveOld), so triggering a full
 re-build. The option if effective only for PROOF protocol > 8 .
 Returns 0 in case of success and -1 in case of error.

 The 'opt' allows to specify whether the .PAR should be just unpacked
 in the existing dir (opt = kUntar, default) or a remove of the existing
 directory should be executed (opt = kRemoveOld), thereby triggering a full
 re-build. The option if effective only for PROOF protocol > 8 .
 Returns 0 in case of success and -1 in case of error.

 Load the specified macro on master, workers and, if notOnClient is
 kFALSE, on the client. The macro file is uploaded if new or updated.
 If existing, the corresponding header basename(macro).h or .hh, is also
 uploaded. The default is to load the macro also on the client.

 the active list. The request will be forwarded to the master
 in direct contact with the worker. If needed, this master will move
 the worker from the active to the inactive list and rebuild the list
 of unique workers.
 Use ord = "*" to deactivate all active workers.

 Modify the worker active/inactive list by making the worker identified by
 the ordinal number 'ord' active (add == TRUE) or inactive (add == FALSE).
 If needed, the request will be forwarded to the master in direct contact
 with the worker. The end-master will move the worker from one list to the
 other active and rebuild the list of unique active workers.
 Use ord = "*" to deactivate all active workers.

 Start a PROOF session on a specific cluster. If cluster is 0 (the
 default) then the PROOF Session Viewer GUI pops up and 0 is returned.
 If cluster is "" (empty string) then we connect to a PROOF session
 on the localhost ("proof://localhost"). Via conffile a specific
 PROOF config file in the confir directory can be specified.
 Use loglevel to set the default loging level for debugging.
 The appropriate instance of TProofMgr is created, if not
 yet existing. The instantiated TProof object is returned.
 Use TProof::cd() to switch between PROOF sessions.
 For more info on PROOF see the TProof ctor.

 Get instance of the effective manager for 'url'
 Return 0 on failure.

 Wrapper around TProofMgr::Reset().

 Get environemnt variables.

 Add an variable to the list of environment variables passed to proofserv
 on the master and slaves

 Remove an variable from the list of environment variables passed to proofserv
 on the master and slaves

 Clear the list of environment variables passed to proofserv
 on the master and slaves

 Save informations about the worker set in the file .workers in the working
 dir. Called each time there is a change in the worker setup, e.g. by
 TProof::MarkBad().
