       profrep profDataVar sortKey ?outFile? ?userTitle?
              This procedure generates a report from data collect
              from the profile command.  ProfDataVar is the  name
              of  the  array  containing the data returned by the
              profile command. SortKey indicates which data value
              to  sort by.  It should be one of "calls", "cpu" or
              "real".  OutFile is the name of file to  write  the
              report   to.    If   omitted,  stdout  is  assumed.
              UserTitle is an  optional  title  line  to  add  to
              output.

              Listed  with  indentation  below  each procedure or
              command is the procedure  call  stack.   The  first
              indented  line being the procedure that invoked the
              reported procedure or command.  The  next  line  is
              the  procedure that invoked the procedure above it,
              and so on.  If no indented  procedures  are  shown,
              the procedure or command was called from the global
              context.  Time actually spent in the global context
              is  listed  on  a line labeled <global>.  Upleveled
              code  is  reported  in  the  context  that  it  was
              executed  in,  not the context that the uplevel was
              called in.
