help using apt-build

[Michael Fothergill <michael.fothergill@googlemail.com>]

Dear Folks,

I tried using apt-build to install a source file:

root@rhubarb:/home/michaelmikef/Downloads# ls -l adun*

-rw-r--r-- 1 michaelmikef michaelmikef 1395 Feb 23 16:36 adun.app_0.81-6.dsc

root@rhubarb:/home/michaelmikef/Downloads# apt-build install adun.app_0.81-6.dsc

W: Unable to locate package adun.app_0.81-6.dsc

Unable to find source candidate for adun.app_0.81-6.dsc

What am I doing wrong here?

Regards

Michael Fothergill
