|  |  C.5 configure 
The purpose of the preceding processes was to create the input files
necessary for configureto run correctly.  You would ship your
project with the generatedscriptand the files in columns,
other input and processes (except `config.cache'), butconfigureis designed to be run by the person installing your
package.  Naturally, you will run it too while you develop your project,
but the files it produces are specific to your development machine, and
are not shipped with your package -- the person installing it later will
runconfigureand generate output files specific to
their own machine. 
Running the configurescript on the build host executes the
various tests originally specified by the `configure.in' file, and
then creates another script, `config.status'.  This new script
generates the `config.h' header file from `config.h.in', and
`Makefile's from the named `Makefile.in's.  Once
`config.status' has been created, it can be executed by itself to
regenerate files without rerunning all the tests.  Additionally, if
`AC_PROG_LIBTOOL' was used, thenltconfigis used to
generate alibtoolscript.
