+To build and install rsync:
$ ./configure
$ make
$ ./configure --help
+Configure tries to figure out if the local system uses group "nobody" or
+"nogroup" by looking in the /etc/group file. (This is only used for the
+default group of an rsync daemon, which attempts to run with "nobody"
+user and group permissions.) You can change the default user and group
+for the daemon by editing the NOBODY_USER and NOBODY_GROUP defines in
+config.h, or just override them in your /etc/rsyncd.conf file.
+
As of 2.4.7, rsync uses Eric Troan's popt option-parsing library. A
-cut-down copy of release 1.5 is included in the rsync distribution,
-and will be used it there is no popt library on your build host, or if
+cut-down copy of a recent release is included in the rsync distribution,
+and will be used if there is no popt library on your build host, or if
the --with-included-popt option is passed to ./configure.
+
+If you configure using --enable-maintainer-mode, then rsync will try
+to pop up an xterm on DISPLAY=:0 if it crashes. You might find this
+useful, but it should be turned off for production builds.
+
+MAKE COMPATIBILITY
+------------------
+
+Note that Makefile.in has a rule that uses a wildcard in a prerequisite. If
+your make has a problem with this rule, you will see an error like this:
+
+ Don't know how to make ./*.c
+
+You can change the "proto.h-tstamp" target to omit its prerequisite args,
+but keep in mind that this will make a manual removal of "proto.h-tstamp"
+necessary anytime the function prototypes change.
+
+RPM NOTES
+---------
+
+Under packaging you will find .spec files for several distributions.
+The .spec file in packaging/lsb can be used for Linux systems that
+adhere to the Linux Standards Base (e.g., RedHat and others).
+
+HP-UX NOTES
+-----------
+
+The HP-UX 10.10 "bundled" C compiler seems not to be able to cope with
+ANSI C. You may see this error message in config.log if ./configure
+fails:
+
+ (Bundled) cc: "configure", line 2162: error 1705: Function prototypes are an ANSI feature.
+
+Install gcc or HP's "ANSI/C Compiler".
+
+MAC OSX NOTES
+-------------
+
+Some versions of Mac OS X (Darwin) seem to have an IPv6 stack, but do
+not completely implement the "New Sockets" API.
+
+<http://www.ipv6.org/impl/mac.html> says that Apple started to support
+IPv6 in 10.2 (Jaguar). If your build fails, try again after running
+configure with --disable-ipv6.
+
+IBM AIX NOTES
+-------------
+
+IBM AIX has a largefile problem with mkstemp. See IBM PR-51921.
+The workaround is to append the below to config.h
+ #ifdef _LARGE_FILES
+ #undef HAVE_SECURE_MKSTEMP
+ #endif
