+FreePort
+========
+
+Get a free open TCP port that is ready to use.
+
+## Command Line Example:
+```bash
+# Ask the kernel to give us an open port.
+export port=$(freeport)
+
+# Start standalone httpd server for testing
+httpd -X -c "Listen $port" &
+
+# Curl local server on the selected port
+curl localhost:$port
+```
+
+## Golang example:
+```go
+package main
+
+import "github.com/phayes/freeport"
+
+func main() {
+	port, err := freeport.GetFreePort()
+	if err != nil {
+		log.Fatal(err)
+	}
+	// port is ready to listen on
+}
+
+```
+
+## Installation
+
+#### Mac OSX
+```bash
+brew install phayes/repo/freeport
+```
+
+
+#### CentOS and other RPM based systems
+```bash
+wget https://github.com/phayes/freeport/releases/download/1.0.2/freeport_1.0.2_linux_386.rpm
+rpm -Uvh freeport_1.0.2_linux_386.rpm
+```
+
+#### Ubuntu and other DEB based systems
+```bash
+wget wget https://github.com/phayes/freeport/releases/download/1.0.2/freeport_1.0.2_linux_amd64.deb
+dpkg -i freeport_1.0.2_linux_amd64.deb
+```
+
+#### Building From Source
+```bash
+sudo apt-get install golang                    # Download go. Alternativly build from source: https://golang.org/doc/install/source
+go get github.com/phayes/freeport

-This program reads a file containing function prototypes
-(like syscall_aix.go) and generates system call bodies.
-The prototypes are marked by lines beginning with "//sys"
-and read like func declarations if //sys is replaced by func, but:
-	* The parameter lists must give a name for each argument.
-	  This includes return parameters.
-	* The parameter lists must give a type for each argument:
-	  the (x, y, z int) shorthand is not allowed.
-	* If the return parameter is an error number, it must be named err.
-	* If go func name needs to be different than its libc name,
-	* or the function is not in libc, name could be specified
-	* at the end, after "=" sign, like
-	  //sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
-

-This program will generate three files and handle both gc and gccgo implementation:
-  - zsyscall_aix_ppc64.go: the common part of each implementation (error handler, pointer creation)
-  - zsyscall_aix_ppc64_gc.go: gc part with //go_cgo_import_dynamic and a call to syscall6
-  - zsyscall_aix_ppc64_gccgo.go: gccgo part with C function and conversion to C type.
-
- The generated code looks like this

-	  This includes return parameters.
-	* The parameter lists must give a type for each argument:
-	  the (x, y, z int) shorthand is not allowed.
-	* If the return parameter is an error number, it must be named err.
-	* If go func name needs to be different than its libc name,
-	* or the function is not in libc, name could be specified
