Recently I install roundup in my host, at last I
successfully
installed it. But I saw some bugs or problem in the
installation
document.

After run roundup-admin install command, I follow the
direction:

--------------------------------------------cut
begin-------------------------------------

You will now be directed to edit the tracker
configuration and initial
schema. At a minimum, you must set MAILHOST,
TRACKER_WEB, MAIL_DOMAIN
and ADMIN_EMAIL. The configuration file uses Python
syntax, so almost
every value must be 'quoted' using single or double
quotes. If you get
stuck, and get configuration file errors, then see the
tracker
configuration section of the customisation documentation.

If you just want to get set up to test things quickly
(and follow the
instructions in step 3 below), you can even just set
the TRACKER_WEB
variable to:

TRACKER_WEB = 'http://localhost:8080/support/'

------------------------------------cut
end---------------------------------

The exact thing is you should change the option web in
session
[tracker], option host, domain in session [mail], email
in session
[admin], not the MAILHOST, TRACKER_WEB, MAIL_DOMAIN and
ADMIN_EMAIL(these are program details). And option web(not
TRACKER_WEB) should be http://localhost:8080/support/,
don't need be
quoted with single quotes.
