8 A directory holding the output of the build system. The build
9 system attempts to isolate all file modifications to this
10 directory. By convention, object directories are commonly
11 directories under the source directory prefixed with **obj-**.
15 A shell script used to configure the build system.
18 A generated shell script which detects the current system
19 environment, applies a requested set of build configuration
20 options, and writes out metadata to be consumed by the build
24 An executable file produced by **configure** that takes the
25 generated build config and writes out files used to build the
26 tree. Traditionally, config.status writes out a bunch of
30 A file containing metadata describing file installation rules.
31 A large part of the build system consists of copying files
32 around to appropriate places. We write out special files
33 describing the set of required operations so we can process the
34 actions efficiently. These files are install manifests.
37 A build performed with an initially empty object directory. All
38 build actions must be performed.
41 A build performed with the result of a previous build in an
42 object directory. The build should not have to work as hard because
43 it will be able to reuse the work from previous builds.
46 An API for accessing a common and limited subset of the build and
47 run-time configuration. See :ref:`mozinfo`.
