1216 \`configure' configures less 1 to adapt to many kinds of systems.
1217
1218 Usage: $0 [OPTION]... [VAR=VALUE]...
1219
1220 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1221 VAR=VALUE.  See below for descriptions of some of the useful variables.
1222
1223 Defaults for the options are specified in brackets.
1224
1225 Configuration:
1226   -h, --help              display this help and exit
1227       --help=short        display options specific to this package
1228       --help=recursive    display the short help of all the included packages
1229   -V, --version           display version information and exit
1230   -q, --quiet, --silent   do not print \`checking ...' messages
1231       --cache-file=FILE   cache test results in FILE [disabled]
1232   -C, --config-cache      alias for \`--cache-file=config.cache'
1233   -n, --no-create         do not create output files
1234       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1235
1236 Installation directories:
1237   --prefix=PREFIX         install architecture-independent files in PREFIX
1238                           [$ac_default_prefix]
1239   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1240                           [PREFIX]
1241
1242 By default, \`make install' will install all the files in
1243 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1244 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1245 for instance \`--prefix=\$HOME'.
1246
1247 For better control, use the options below.
1248
1249 Fine tuning of the installation directories:
1250   --bindir=DIR            user executables [EPREFIX/bin]
1251   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1292   --with-regex={auto,gnu,pcre,posix,regcmp,re_comp,regcomp,regcomp-local,none}  Select a regular expression library  auto
1293   --with-editor=PROGRAM   use PROGRAM as the default editor vi
1294
1295 Some influential environment variables:
1296   CC          C compiler command
1297   CFLAGS      C compiler flags
1298   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1299               nonstandard directory <lib dir>
1300   LIBS        libraries to pass to the linker, e.g. -l<library>
1301   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1302               you have headers in a nonstandard directory <include dir>
1303   CPP         C preprocessor
1304
1305 Use these variables to override the choices made by `configure' or to help
1306 it to find libraries and programs with nonstandard names/locations.

1308 Report bugs to the package provider.
