Autoconf - Site Configuration Go to the previous , next section. Site Configuration configure scripts support several kinds of local configuration decisions. There are ways for users to specify where external software packages are, include or exclude optional features, install programs under modified names, and set default values for configure options.
Some packages require, or can optionally use, other software packages which are already installed.
The user can give configure command line options to specify which such external software to use. Whether each package is used or not by default, and which arguments are valid, is up to you. The name package indicates another software package that this program should work with. It should consist only of alphanumeric characters and dashes. Avoid tabs in the help string.
