The text is almost completely from GvR's essay on packages; some
introductory paragraphs have been removed, and everything after the
'Details' section in the HTML has been dropped (seems too technical).  A
paragraph has been added after the sample package layout stating that there
must be a file called__init__.py in a directory to make it a package.

# later release.

Use logical (& consistent) markup.

Added a see-also section at the end.

Need to add \optional{} to sort argument too.

Made x a \var in descr of pop.

Fixed note for pop() and mentioned that it is experimental.

Also added pop to index.

# The brackets generated by \optional{} are real ugly.  Alas...

article().

article() commands.

.mirrorinfo.  Fix by me to call string.lstrip(filename) to cope with a
bug in strop.strip() in Python 1.4.  Additionally, I changed all print
statements that print filenames etc. to put them in backquotes so that

(such as a space...).

groupdict() and findall().

exception waiting to happen next...

should never be called, so this isn't really needed, but this

didn't want to commit until it had been tested.  I presume that it
works in Grail.)

string.  Added groupdict() to MatchObject -- return the named groups
as a dict.  Added default argument to groups() to specify what to
return for unmatching groups; groupdict() also has this.

the '%' should be put back in.

cmd, multifile and smtplib.

the filename contains at least a rudimentary pathname.
(The bad part is that we need to call getcwd() because only a prefix
of ".\\" is not enough -- we prefix the drive letter.)
