Package Building -- Start to Finish

Obtain the source code ([g[z]]tarball, zip)
Save the full url
Use timestamp preserving tools to fetch it (lftp, ncftp)

Perform a test build of the package
$ tar xzvf acmetool-1.2.1.tar.gz
$ cd acmetool-1.2.1
$ ./configure --prefix=/usr
$ make
$ make install DESTDIR=/tmp/acmetool

List the files in /tmp/acmetool
$ find /tmp/acmetool -print
Save this list -- it will come in handy when creating the spec file
