Splitting up a too-wide text file

[Don Thomson]

I've got a file of ASCII text that has lines that are too long to easily
print, formatted in columns.  I'd like to run the file through a filter that
will essentially break each page in half horizontally at a column break and
place the right-hand side of the broken-off text on a new following page,
resulting in a new file of reasonable width.  I've got a few relatively
inelegant solutions in mind, but am interested in suggestions on how other
people might approach the problem with an appropriate combination of UNIX
tools.  Any ideas?
