+autoconf-macros
+===============
+
+The purpose of Nagios autoconf-macros is to have a central place for
+autoconf macros that can be maintained in one place, but be used by any
+of the Nagios software. It is intended to be used as a git subtree.
+See the [Usage](#usage) and [References](#references) sections below.
+
+Since this project will be included in several parent projects, any
+changes must be as project-neutral as possible.
+
+Make sure to check out the [CHANGELOG](CHANGELOG.md) for relevant 
+information, as well.
+
+
+Contents
+--------
+
+The collection consists of the following macros:
+
+### AX_NAGIOS_GET_OS alias AC_NAGIOS_GET_OS
+
+> Output Variable : `opsys`
+
+This macro detects the operating system, and transforms it into a generic
+label. The most common OS's that use Nagios software are recognized and
+used in subsequent macros.
+
+### AX_NAGIOS_GET_DISTRIB_TYPE alias AC_NAGIOS_GET_DISTRIB_TYPE
+
+> Output Variables : `dist_type`, `dist_ver`
+
+This macro detects the distribution type. For Linux, this would be rh
+(for Red Hat and derivitives), suse (OpenSUSE, SLES, derivitives), gentoo
+(Gentoo and derivitives), debian (Debian and derivitives), and so on.
+For BSD, this would be openbsd, netbsd, freebsd, dragonfly, etc. It can
+also be aix, solaris, osx, and so on for Unix operating systems.
+
+### AX_NAGIOS_GET_INIT alias AC_NAGIOS_GET_INIT
+
+> Output Variable : `init_type`
+
+This macro detects what software is used to start daemons on bootup
+or on request, generally knows as the "init system". The init_type
+will generally be one of sysv (many), bsd (Slackware), newbsd (*BSD),
+launchd (OS X), smf10 or smf11 (Solaris), systemd (newer Linux),
+gentoo (older Gentoo), upstart (several), or unknown.
+
+### AX_NAGIOS_GET_INETD alias AC_NAGIOS_GET_INETD
+
+> Output Variable : `inetd_type`
+
+This macro detects what software is used to start daemons or services
+on demand, which historically has been "inetd". The inetd_type
+will generally be one of inetd, xinetd, launchd (OS X), smf10 or smf11
+(Solaris), systemd (newer Linux), upstart (several), or unknown.
+
+### AX_NAGIOS_GET_PATHS alias AC_NAGIOS_GET_PATHS
+
+> Output Variables : **many!**
+
+This macro determines the installation paths for binaries, config files,
+PID files, and so on. For a "standard" install of Nagios, NRPE, NDO Utils,
+etc., most will be in the /usr/local/nagios hierarchy with startup files
+located in /etc. For distributions or software repositories, the
+"--enable-install-method=os" option can be used. This will determine the
+O/S dependant directories, such as /usr/bin, /usr/sbin, /var/lib/nagios,
+/usr/lib/nagios, etc. or for OS X, /Library/LaunchDaemons.
+
+### AX_NAGIOS_GET_FILES alias AC_NAGIOS_GET_FILES
+
+> Output Variables : `src_init`, `src_inetd`, `src_tmpfile`
+
+Each Nagios project will have a top-level directory named "/startup/".
+In that directory will be "*.in" files for the various "init_type" and
+"inetd_type" systems. This macro will determine which file(s) from
+that directory will be needed.
+
+### AX_NAGIOS_GET_SSL alias AC_NAGIOS_GET_SSL
+
+> Output Variables : `HAVE_KRB5_H`, `HAVE_SSL`, `SSL_INC_DIR`, `SSL_LIB_DIR`, `CFLAGS`, `LDFLAGS`, `LIBS`
+
+This macro checks various directories for SSL libraries and header files.
+The searches are based on known install locations on various operating
+systems and distributions, for openssl, gnutls-openssl, and nss_compat_ossl.
+If it finds the headers and libraries, it will then do an `AC_LINK_IFELSE`
+on a simple program to make sure a compile and link will work correctly.
+
+
+Usage
+-----
+
+This repo is intended to be used as a git subtree, so changes will
+automatically propogate, and still be reasonably easy to use.
+
+* First, Create, checkout, clone, or branch your project. If you do an
+`ls -AF` it might look something like this:
+
+           .git/      .gitignore    ChangeLog   LICENSE   Makefile.in
+           README     configure.ac  include/    src/
+
+* Then make a reference to _this_ project inside your project.
+
+           git remote add autoconf-macros git@github.com:NagiosEnterprises/autoconf-macros
+           git subtree add --prefix=macros/ autoconf-macros master
+
+* After executing the above two commands, if you do an `ls -AF` now,
+it should look like this:
+
+           .git/      .gitignore    ChangeLog   LICENSE   Makefile.in
+           README     configure.ac  include/    macros/   src/
+
+* The `macros/` directory has been added.
+
+* Now do a `git push` to save everything.
+
+* If you make any changes to autoconf-macros, commit them separately
+from any parent-project changes to keep from polluting the commit
+history with unrelated comments.
+
+* To submit your changes to autoconf-macros:
+
+           git subtree push --prefix=macros autoconf-macros peters-updates
+This will create a new branch called `peters-updates`. You then need to
+create a _pull request_ to get your changes merged into autoconf-macros
+master.
+
+* To get the latest version of `autoconf-macros` into your parent project:
+
+           git subtgree pull --squash --prefix=macros autoconf-macros master
+
+
+References
+----------
+
+Now that autoconf-macros is available to your project, you will need to
+reference it.
+
+* Create (or add these lines to) file `YourProject/aclocal.m4`
+
+           m4_include([macros/ax_nagios_get_os])
+           m4_include([macros/ax_nagios_get_distrib])
+           m4_include([macros/ax_nagios_get_init])
+           m4_include([macros/ax_nagios_get_inetd])
+           m4_include([macros/ax_nagios_get_paths])
+           m4_include([macros/ax_nagios_get_files])
+           m4_include([macros/ax_nagios_get_ssl])
+
+* In your `YourProject/configure.ac` add the following lines. A good place
+to put them would be right after any `AC_PROG_*` entries:
+
+           AC_NAGIOS_GET_OS
+           AC_NAGIOS_GET_DISTRIB_TYPE
+           AC_NAGIOS_GET_INIT
+           AC_NAGIOS_GET_INETD
+           AC_NAGIOS_GET_PATHS
+           AC_NAGIOS_GET_FILES
+
+* If you need SSL functionality, add the following to `YourProject/configure.ac`
+where you want to check for SSL:
+
+           AC_NAGIOS_GET_SSL
+
+* You will now be able to reference any of the variables in `config.h.in`
+and any files listed in the `AC_CONFIG_FILES` macro in `configure.ac`.
