1235\`configure' configures tcsh 6.18.01 to adapt to many kinds of systems.
1236
1237Usage: $0 [OPTION]... [VAR=VALUE]...
1238
1239To assign environment variables (e.g., CC, CFLAGS...), specify them as
1240VAR=VALUE.  See below for descriptions of some of the useful variables.
1241
1242Defaults for the options are specified in brackets.
1243
1244Configuration:
1245  -h, --help              display this help and exit
1246      --help=short        display options specific to this package
1247      --help=recursive    display the short help of all the included packages
1248  -V, --version           display version information and exit
1249  -q, --quiet, --silent   do not print \`checking ...' messages
1250      --cache-file=FILE   cache test results in FILE [disabled]
1251  -C, --config-cache      alias for \`--cache-file=config.cache'
1252  -n, --no-create         do not create output files
1253      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1254
1255Installation directories:
1256  --prefix=PREFIX         install architecture-independent files in PREFIX
1257                          [$ac_default_prefix]
1258  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1259                          [PREFIX]
1260
1261By default, \`make install' will install all the files in
1262\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1263an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1264for instance \`--prefix=\$HOME'.
1265
1266For better control, use the options below.

1320Some influential environment variables:
1321  CC          C compiler command
1322  CFLAGS      C compiler flags
1323  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1324              nonstandard directory <lib dir>
1325  LIBS        libraries to pass to the linker, e.g. -l<library>
1326  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1327              you have headers in a nonstandard directory <include dir>
1328  CPP         C preprocessor
1329
1330Use these variables to override the choices made by `configure' or to help
1331it to find libraries and programs with nonstandard names/locations.
