10.8 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.  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.

'--version'
     Print the version of Autoconf used to generate the 'configure'
     script, and exit.

'configure' also accepts some other, not widely useful, options.
