Feature request: postformatter plugin for linking between entries

What I want is a way to link from one pyblosxom story to other stories
on the same blog. By link I mean HTML hyperlinks in the HTML output of
the blog. The reason I can't just use the normal permalink for the entry
is because I sync different copies of the blog on different machines, so
the part of the URL that comes before /pyblosxom.cgi changes. I need a
way to make a relative not absolute link between entries, so that if I
move my blog around all the hyperlinks between posts will keep working.
Relative links like this don't appear to be possible with pyblosxom,
once you realise that you may be viewing an entry on its permalink page
or on some category or month page, index page, etc. You know where you
want to link to but you don't know where you are linking _from_.

Basically you need to be able to put some text like $base in your
stories and have pyblosxom expand it to, for example,
http://127.0.0.1/cgi-bin/pyblosxom.cgi so then you could link to other
stories by doing <a href="$base/folder1/folder2/story">. Or
alternatively, some wiki-like syntax like
[Hyperlink][/folder1/folder2/story] that pyblosxom would expand to (for
example) <a
href="http://127.0.0.1/cgi-bin/pyblosxom.cgi/folder1/folder2/story">Hyperlink</a>/

wbgwiki sounds like it does something very much like that, but it seems
to separate wiki files from blog files and put each in a different
folder.

Also my request is the same as one I found elsewhere on this mailing
list:

"Mmm...  If I understand you correctly, you want to link between
entries.  PyBlosoxm doesn't make that easy to do.  I think you're
going to have to write a postformatter plugin or find someone who has
already written one that looks through your entry for some kind of
syntactical indicator and replaces the syntactical indicator with the
full url for the target entry.

I don't think this would be hard to write.  If you can't find anything
else out there that does this and you don't want to try writing a
plugin on your own, poke me and I can write it."

Thanks
