    If numRevisionsOrNil is notNil, it limits the number of revision records returned -

     only numRevions of the newest revision infos will be collected.

     The returned information is a structure (IdentityDictionary)

     filled with:

            #container          -> the RCS/CVS container file name 

            #cvsRoot            -> the CVS root (repository) 

            #filename           -> the actual source file name

            #newestRevision     -> the revisionString of the newest revision

            #numberOfRevisions  -> the number of revisions in the container (nil for all)

            #revisions          -> collection of per-revision info (see below)

            firstRevOrNil / lastRevOrNil specify from which revisions a logEntry is wanted:

             -If firstRevOrNil is nil, the first revision is the initial revision

              otherwise, the log starts with that revision.

             -If lastRevOrNil is nil, the last revision is the newest revision

              otherwise, the log ends with that revision.

             -If both are nil, all logEntries are extracted.

             -If both are 0 (not nil), no logEntries are extracted (i.e. only the header).

            per revision info consists of one record per revision:

              #revision              -> the revision string

              #author                -> who checked that revision into the repository

              #date                  -> when was it checked in

              #state                 -> the RCS state

              #numberOfChangedLines  -> the number of changed line w.r.t the previous

              #logMessage            -> the checkIn log message

            revisions are ordered newest first 

            (i.e. the last entry is for the initial revision; the first for the most recent one)

            Attention: if state = 'dead' that revision is no longer valid.
