flyspray 
Started playing with flyspray v0.9.7. Had everything I needed already installed but the adodb. So load that up and make sure it works fine with a test script… no problems. Download flyspray and go to the online docs to see how to install. Only one problem - there isn’t any docs online for installation - features yeah - but no installation or setup. so I unzip it on the desktop to see if it has a README within it. Nope. Hmmm. Scour the online stuff again and still nothing. Go back to the unzipped file - there is a folder docs.. didn’t notice that before. Inside is a README that tells me to go to the INSTALL.txt.
(summery of first couple steps)
step 1 - download flyspray to someplace the web server can access (I just put it on the web root).
step 2 - create a mysql database - done
step 3 - go to the index page and follow the script.
So I go there (ended up putting a directory block in the Apache config so I don’t have to type in the whole url - I’m lazy like that - now that I know how 
). What do I see - a sh#t ton of “Notice: undefined index…” errors all over the place (not very impressed with that). Crap I can barely make out what the page is supposed to look like. Go to the header.php file and edit it so that the notices go away
[php]error_reporting(E_ALL ^ E_NOTICE);[/php].
Ok now I can see it. Time to log in.. Crap what was I supposed to use again - look it up in the INSTALL.txt and log in (step 4 and onward). Move around inside and play with it.
General “feel” for it? Honestly it immediately turned me off when all those E_NOTICE’s popped up. Also had php code displaying where it shouldn’t of been (like in form fields and on buttons). Sloppy programming immediately came to mind (snobbish of me I know). Other then that - very easy to use (even easier the Mantis) though it doesn’t seem to have as many capabilities and isn’t nearly as polished. I assume this is why it still hasn’t made it to v1.
Opinion - I’ll wait a little bit longer for this one to develop. The docs need to minimally state where the INSTALL.txt file for it’s INSTALLATION section (that was also an immediate turn off). When it hits v1.0 I might take a look at it again.
