How do I use template.py templates?

For basic doc and some code snippets, see template.py doc

To display your page from inside a web.py app, just do
```
    homepage = template.Template(open("homepage.tmpl").read())
    print homepage()
```
Why are the urls just one long list?

If they were a dictionary, they wouldn't be ordered. If it was a list of tuples, then it'd be a lot more typing.
How do I serve static files such as JavaScripts or images like PNG and JPG with the web.py server?

Create a directory (also known as a folder) called static in the location of the script that runs the web.py server. Then place the static files you wish to server in the static folder. For example, the URL http://localhost/static/logo.png will send the image ./static/logo.png to the client.
Where can I go for additional help?

Google Groups has a web.py group that is quite helpful.
How can I change the default "not found" page?

You can write your own custom notfound handler and assign it to web.webapi.notfound
```
    def my_notfound(): 
        print "MY OWN NOT FOUND" 
    web.webapi.notfound = my_notfound
```
How can i get auto completion in python after loading the webpy module?

In IPython, after importing webpy auto completion may no longer work. You can still use 'python' with auto completion feature. Try it out directly. Fire up 'python':
```
    import readline, rlcompleter; readline.parse_and_bind("tab: complete")
```
and tab it! :-)

To make in sort that this will be run default when you fire up 'python'. Make a file called '~/.pythonstartup.py' and put the import line in it. Then set the 'PYTHONSTARTUP' environment variable to point to that file.

With my bash, i do it like following; edit ~/.bashrc and add:
```
    export PYTHONSTARTUP=~/.pythonstartup.py
```
Why can't I access the database?

If you're trying to access the database from a non-web-serving thread (e.g. you created a new thread or you never started serving web pages) then you need to run web.load(). Sorry, this will be fixed in web.py 0.3.
Can I iterate over an IterBetter multiple times?

No. Do ib = list(ib) first to turn it from an IterBetter into a list.
How do I debug print to the console?

web.debug("I will get printed to the console and not the body of the webpage")
I stumbled over a bug in web.py. Where can I file it?

Go to the webpy launchpad site, login (or register if you have to) and click on "report a bug".
