PIPE stands for Python Interactive Process Enabler. It provides Expect-like
functionality for Python using object-oriented constructs. PIPE was written
by John F. Croix ([email protected] or [email protected]).

This is version 1.0 of PIPE. The PIPE distribution consists of the following
two files:
* pipe-1.0.README (this file)
* pipe-1.0.tgz (a tar'ed, gzip'ed file)
The source code and documentation can be found in pipe-1.0.tgz and consists

V1.0: Fixed a race condition when reading data line by line. Sometimes the
current data in the buffer wouldn't have a carriage return in it to
distinguish an end-of-line. The code would read more data from the
subprocess. The bug is that, even with this new data, there may still
not be a carriage return in the data. The old code simply tried once to
get new data. The new code loops until some type of error condition is
detected (ie TIMEOUT) or until a carriage return can be found.

Added functions MatchLineAfter() and MatchLineBefore() to supply patterns
which should be matched after and before any other patterns when
performing line-by-line pattern matching. Originally the code used the
patterns supplied by MatchAfter() and MatchBefore(). The problem was
that it wasn't necessarily possible to use the same regular expression
when matching line-by-line as it was when matching against the entire
input stream. Now the two are separate from each other.
