+PROHST is a preliminary version of a utility to process the profile
+file produced by the PROFIL utility of MSDOS.
+Those of you familiar with MS-Pascal or MS-Fortran will have little
+difficulty in understanding how the parameters work. There are three,
+the .PRF filename, an optional histogram file (default extension .HST,
+default name same as the .PRF file) and an optional link map. If the
+link map was produced with the line number options PROHST will try
+and relate buckets to line numbers. Otherwise, it will relate it to
+module offsets. If you specify no map file (the default), addresses
+relative to the start of the program will be used. The default extension
+for the map file is .MAP.
+
+a:prohst f;
+
+this will produce a histogram for the file f.prf in f.hst and no map file
+will be assumed.
+
+a:prohst f,,;
+
+this will produce a histogram for f.prf in f.hst and expects a f.map file.
+
+a:prohst f,g,k
+
+this produces a histogram for f.prf in g.hst and expects a map file k.map.
+
+Note that if you select the map option with line numbers, the program will
+appear to be looping. Never fear, go and have lunch or some other time
+consuming pastime, and you will be suprised how long it took to produce
+such a small file. Also, some of the line number/bucket correspondances are
+not what they might be. Future version shoudl fix this. If you make a better
+version, be sure to let me have a copy.
