1257 \`configure' configures fswebcam 20091224 to adapt to many kinds of systems.
1258
1259 Usage: $0 [OPTION]... [VAR=VALUE]...
1260
1261 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1262 VAR=VALUE.  See below for descriptions of some of the useful variables.
1263
1264 Defaults for the options are specified in brackets.
1265
1266 Configuration:
1267   -h, --help              display this help and exit
1268       --help=short        display options specific to this package
1269       --help=recursive    display the short help of all the included packages
1270   -V, --version           display version information and exit
1271   -q, --quiet, --silent   do not print \`checking...' messages
1272       --cache-file=FILE   cache test results in FILE [disabled]
1273   -C, --config-cache      alias for \`--cache-file=config.cache'
1274   -n, --no-create         do not create output files
1275       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1276
1277 Installation directories:
1278   --prefix=PREFIX         install architecture-independent files in PREFIX
1279                           [$ac_default_prefix]
1280   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1281                           [PREFIX]
1282
1283 By default, \`make install' will install all the files in
1284 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1285 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1286 for instance \`--prefix=\$HOME'.
1287
1288 For better control, use the options below.

1290 Fine tuning of the installation directories:
1291   --bindir=DIR            user executables [EPREFIX/bin]
1292   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1325   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]

1330 Some influential environment variables:
1331   CC          C compiler command
1332   CFLAGS      C compiler flags
1333   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1334               nonstandard directory <lib dir>
1335   LIBS        libraries to pass to the linker, e.g. -l<library>
1336   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1337               you have headers in a nonstandard directory <include dir>
1338   CPP         C preprocessor
1339
1340 Use these variables to override the choices made by `configure' or to help
1341 it to find libraries and programs with nonstandard names/locations.

3665    Here is a matrix of mmap possibilities:
3666         mmap private not fixed
3667         mmap private fixed at somewhere currently unmapped
3668         mmap private fixed at somewhere already mapped
3669         mmap shared not fixed
3670         mmap shared fixed at somewhere currently unmapped
3671         mmap shared fixed at somewhere already mapped
3672    For private mappings, we should verify that changes cannot be read()
3673    back from the file, nor mmap's back from the file at a different
3674    address.  (There have been systems where private was not correctly
3675    implemented like the infamous i386 svr4.0, and systems where the
3676    VM page cache was not coherent with the file system buffer cache
3677    like early versions of FreeBSD and possibly contemporary NetBSD.)
3678    For shared mappings, we should conversely verify that changes get
3679    propagated back to all the places they're supposed to be.
3680
3681    Grep wants private fixed already mapped.
3682    The main things grep needs to know about mmap are:
3683    * does it exist and is it safe to write into the mmap'd area
3684    * how to use it (BSD variants)  */
