The postview program was written to post-process a WordStar preview.ws file
created by "printing" a document to a file using the "prview" printer driver.
That process generates a file with a fixed name, namely "prview.ws".

The idea was to produce a pure ASCII version of the original document stripped
of all the formatting instructions, dot commands and so on.  The "prview.ws"
file is exactly that except that it has eight spaces prepended to each line.

The main purpose of postview is to remove those eight leading spaces.  Other,
less important stuff happens at the same time.

The first and only usage of this program was to generate an ASCII version of
the manual for the Z8E debugger.
