From AMule Project FAQ
tar is a command-line program for creating and unpacking file archives. It is widely used in the Unix environment.
tar archives are identified by the ".tar" suffix. If they have been compressed, the suffix will be "tar.gz" or "tar.bz2".
To compile the AMule source code, you first need to unpack the .tar archive. To do this, type
- $ tar xvjf [amule-source-tarball]
If you want to unpack the archive in a location other than the current directory, use the -C [destination] flag.
- $ tar xvjf aMule-CVS-20061202.tar.bz2 -C /usr/local/src
