bash: Operation Controls

 
 10.7 Operation Controls
 =======================
 
 'configure' recognizes the following options to control how it operates.
 
 '--cache-file=FILE'
      Use and save the results of the tests in FILE instead of
      './config.cache'.  Set FILE to '/dev/null' to disable caching, for
      debugging 'configure'.
 
 '--help'
      Print a summary of the options to 'configure', and exit.
 
 '--quiet'
 '--silent'
 '-q'
      Do not print messages saying which checks are being made.
 
 '--srcdir=DIR'
      Look for the Bash source code in directory DIR.  Usually
      'configure' can determine that directory automatically.
 
 '--version'
      Print the version of Autoconf used to generate the 'configure'
      script, and exit.
 
    'configure' also accepts some other, not widely used, boilerplate
 options.  'configure --help' prints the complete list.
