1253\`configure' configures tcsh 6.21.00 to adapt to many kinds of systems.
1254
1255Usage: $0 [OPTION]... [VAR=VALUE]...
1256
1257To assign environment variables (e.g., CC, CFLAGS...), specify them as
1258VAR=VALUE.  See below for descriptions of some of the useful variables.
1259
1260Defaults for the options are specified in brackets.
1261
1262Configuration:
1263  -h, --help              display this help and exit
1264      --help=short        display options specific to this package
1265      --help=recursive    display the short help of all the included packages
1266  -V, --version           display version information and exit
1267  -q, --quiet, --silent   do not print \`checking ...' messages
1268      --cache-file=FILE   cache test results in FILE [disabled]
1269  -C, --config-cache      alias for \`--cache-file=config.cache'
1270  -n, --no-create         do not create output files
1271      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1272
1273Installation directories:
1274  --prefix=PREFIX         install architecture-independent files in PREFIX
1275                          [$ac_default_prefix]
1276  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1277                          [PREFIX]
1278
1279By default, \`make install' will install all the files in
1280\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1281an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1282for instance \`--prefix=\$HOME'.
1283
1284For better control, use the options below.

1336  --with-hesiod=PREFIX    Use Hesiod lookup for ~ expansion
1337
1338Some influential environment variables:
1339  CC          C compiler command
1340  CFLAGS      C compiler flags
1341  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1342              nonstandard directory <lib dir>
1343  LIBS        libraries to pass to the linker, e.g. -l<library>
1344  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1345              you have headers in a nonstandard directory <include dir>
1346  CPP         C preprocessor
1347
1348Use these variables to override the choices made by `configure' or to help
1349it to find libraries and programs with nonstandard names/locations.
