Version 0.9.0
	Added an extension framework, register_foo_fn and invoke_foo_fn
	where foo is one of "cap" (capability, returns file descriptor) or
	"info" (returns string)

	Added priv_popen_as(), priv_unlink(), and priv_wait4() methods.
	Changed how priv_rerunas works slightly.  Since the prototype
	to priv_rerunas() changed, the major number of the library has
	been bumped to 1.

	Better support of systems without PAM.  At least it ought to compile
	now.

Version 0.8.4:
	Support Solaris 9
	Add better autoconf tests to give us a shot at supporting other
	currently-untested platforms.

Version 0.8.3:
	Support Macintosh OS X
	Moved more/all debug output to syslog.
	Added man pages.
	Fixed a bug where privman.h might include files that didn't exist
	on the target system.
	If the "setuid()" call fails in priv_init(), blow up.

Version 0.8.2:
	Moved some debug output to syslog.
	Added proper namespaces for C++ classes to fix problems with
	newer g++ versions.
	Added priv_pam_fail_delay.
	Fixed some ordering issues in autogen.sh that let it work with a
	wider range of auto-tool versions.

Version 0.8.1:
	Improved some comments.
	Added config requirement for priv_runas.

Version 0.8:
	Added support for "priv_rerunas" and "priv_execve".  This should
	software that needs to do a uid transition at some midpoint and
	continue.  You'll still have to hack your software some, as
	priv_rerunas falls out of priv_init a second time, but I found
	that this functionality handled FTPD.

Version 0.5:
	Initial release.  Handles file open, bind, and various PAM functions
	in addition to fork and daemon.  Sufficient to port httpd, but not
	sufficient for FTPD or other authenticating servers.
