15.9 configure Invocation
configure recognizes the following options to control how it
operates.
     
- --help- -h
- Print a summary of the options to configure, and exit.
     
 
- --version- -V
- Print the version of Autoconf used to generate the configure
script, and exit.
     
 
- --cache-file=file
- Enable the cache: use and save the results of the tests in file,
traditionally config.cache.  file defaults to
/dev/null to disable caching.
     
 
- --config-cache- -C
- Alias for --cache-file=config.cache.
     
 
- --quiet- --silent- -q
- Do not print messages saying which checks are being made.  To suppress
all normal output, redirect it to /dev/null (any error messages
will still be shown).
     
 
- --srcdir=dir
- Look for the package's source code in directory dir.  Usually
configure can determine that directory automatically. 
configure also accepts some other, not widely useful, options. 
Run `configure --help' for more details.
