configure recognizes the following options to control how it operates. 
--cache-file=fileUse and save the results of the tests in file instead of ./config.cache. Set file to /dev/null to disable caching, for debugging configure. 
--helpPrint a summary of the options to configure, and exit. 
--quiet--silent-qDo not print messages saying which checks are being made.
--srcdir=dirLook for the Bash source code in directory dir. Usually configure can determine that directory automatically. 
--versionPrint 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.
