Missing File : startup squid

Sometimes, when you install a new version squid , you can not find "start-up" file.
That was happened to me. I used Ubuntu 10.04 LTS, and tried to install a new version squid, which I have previously downloaded from http://www.squid-cache.org. After installation was finished, there was no "start-up" file.
Below, start-up file, which I have modified. The original file is from squid Mandriva 2009.0. :)

# description: Squid - Internet Object Cache. Internet object caching is \

# a way to store requested Internet objects (i.e., data available \

# via the HTTP, FTP, and gopher protocols) on a system closer to the \

# requesting site than to the source. Web browsers can then use the \

# local Squid cache as a proxy HTTP server, reducing access time as \

# well as bandwidth consumption.
