+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: ./configure [OPTION]...
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [/usr/local]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`/usr/local/bin', \`/usr/local/lib' etc. You can specify
+an installation prefix other than \`/usr/local' using \`--prefix',
+for instance \`--prefix=$HOME'.
+
+For better control, use the options below.
+ --disable-readline Disable line editing support
+ --without-readline Don't use GNU readline even if it is available
+ --without-editline Don't use editline even if it is available
+ --with-readline-includes=DIR Specify where readline include directory is
+ --with-readline-library=DIR Specify where readline lib directory is
+ --with-ncurses-library=DIR Specify where ncurses lib directory is
+ --disable-sechash Disable support for hashes other than MD5
+ --without-nettle Don't use nettle even if it is available
+ --without-nss Don't use NSS even if it is available
+ --without-tomcrypt Don't use libtomcrypt even if it is available
+ --disable-cmdmon Disable command and monitoring support
+ --disable-ntp Disable NTP support
+ --disable-refclock Disable reference clock support
+ --disable-phc Disable PHC refclock driver
+ --disable-pps Disable PPS refclock driver
+ --disable-ipv6 Disable IPv6 support
+ --disable-rtc Don't include RTC even on Linux
+ --disable-privdrop Disable support for dropping root privileges
+ --without-libcap Don't use libcap even if it is available
+ --enable-scfilter Enable support for system call filtering
+ --without-seccomp Don't use seccomp even if it is available
+ --disable-asyncdns Disable asynchronous name resolving
+ --disable-forcednsretry Don't retry on permanent DNS error
+ --without-clock-gettime Don't use clock_gettime() even if it is available
+ --disable-timestamping Disable support for SW/HW timestamping
+ --enable-ntp-signd Enable support for MS-SNTP authentication in Samba
+ --with-ntp-era=SECONDS Specify earliest assumed NTP time in seconds
+ since 1970-01-01 [50*365 days ago]
+ --with-user=USER Specify default chronyd user [root]
+ --with-hwclockfile=PATH Specify default path to hwclock(8) adjtime file
+ --with-pidfile=PATH Specify default pidfile [/var/run/chrony/chronyd.pid]
+ --with-rtcdevice=PATH Specify default path to RTC device [/dev/rtc]
+ --with-sendmail=PATH Path to sendmail binary [/usr/lib/sendmail]
+ --enable-debug Enable debugging support
+
+Fine tuning of the installation directories:
+ --sysconfdir=DIR chrony.conf location [/etc]
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --datarootdir=DIR data root [PREFIX/share]
+ --mandir=DIR man documentation [DATAROOTDIR/man]
+ --docdir=DIR documentation root [DATAROOTDIR/doc/chrony]
+ --localstatedir=DIR modifiable single-machine data [/var]
+ --chronyrundir=DIR location for chrony sockets [LOCALSTATEDIR/run/chrony]
+ --chronyvardir=DIR location for chrony data [LOCALSTATEDIR/lib/chrony]
+
+Overriding system detection when cross-compiling:
+ --host-system=OS Specify system name (uname -s)
+ --host-release=REL Specify system release (uname -r)
+ --host-machine=CPU Specify machine (uname -m)
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ CPPFLAGS C preprocessor flags, e.g. -I<include dir> if you have
+ headers in a nonstandard directory <include dir>
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+
+Use these variables to override the choices made by \`configure' or to help
+it to find libraries and programs with nonstandard names/locations.
