ConfigParser Include Pre-Processor
File-like Object capable of pre-processing include= lines for
a ConfigParser.
The readline function expands lines matching include=(url)
into lines from the url specified. Includes may occur in
included files as well.
Suggested Usage::
cfg = ConfigParser.ConfigParser()
fileobj = confpp( fileorurl )
cfg.readfp(fileobj)

Implementation of File-Like Object readline function. This should be
the only function called by ConfigParser according to the python docs.
We maintain a stack of real FLOs and delegate readline calls to the
FLO on top of the stack. When EOF occurs on the topmost FLO, it is
popped off the stack and the next FLO takes over. include= lines
found anywhere cause a new FLO to be opened and pushed onto the top
of the stack. Finally, we return EOF when the bottom-most (configfile
arg to __init__) FLO returns EOF.
Very Technical Pseudo Code::
def confpp.readline() [this is called by ConfigParser]
open configfile, push on stack
while stack has some stuff on it
line = readline from file on top of stack
pop and continue if line is EOF
if line starts with 'include=' then
error if file is recursive or duplicate
otherwise open file, push on stack
continue
else
return line
return EOF

Returns an absolute url for the (possibly) relative
url specified. The base url used to resolve the
missing bits of url is the url of the file currently
being included (i.e. the top of the stack).

Opens the url specified, pushes it on the stack, and

has previously been included.
