Ubuntu: package versioning conventions...

Hello,

I just loaded the synaptic package manager under ubuntu linux
to download the latest version of the a2ps text to postscript
converter that has been around for quite a wile now and does
an excellent job including printing more than one screen of
text such as computer source code per page.

What puzzles me is the version number: 1:4.14-1 on synaptic
whereas the version appears as simply 4.14 on:
http://ftp.gnu.org/gnu/a2ps/

I have been used to RPM rather than .deb packages but have
never seen a colon used in package versioning so I am puzzled
as to the 1: part of the version number.

I wonder if anyone could kindly explain the numbering convention
to me or even better point me to a document describing how .deb
packages are put together and named (for ubuntu).

Thanks,

John Goche
