| If you want to install a software package, it often has a system-wide location as default (''/usr'', ''/usr/local'' or ''/opt'', most of the time).

| * ''configure'' scripts often have a ''--prefix'' option to specify the install location. Check ''INSTALL'' notes that come with the package, and ''configure --help'' often lists supported options too. | * ''configure'' scripts often have a ''%%--%%prefix'' option to specify the install location.

| * Python source packages often come with a ''setup.py''. When running the ''install'' phase, you can also specify a ''--prefix'' location, or use ''--user'' to install in a location in your home directory. | * Python source packages often come with a ''setup.py''.

| * a package that comes with a ''Makefile'' often has a ''install'' target or some other location where you can set the destination. No real standards here, you may have to read the documentation and/or the makefile. | * a package that comes with a ''Makefile'' often has a ''install'' target or some other location where you can set the destination.
