the readme is a ramble and there's no functionality (yet). couldn't ask
for a better start.

+ljacklm: Linux (kernel 2.6+) and Mac OS X high-level LabJack U12 library and
+C/C++ examples
+03/09/2017
+support@labjack.com
+
+
+This package contains the libljacklm high-level library for the U12 and examples
+written in C.  The examples demonstrate libljacklm library usage.  The library
+is a port of the ljackuw high-level Windows driver, and uses the Exodriver for
+low-level USB communications.  The functions are documented in section 4 of the
+U12 User's Guide and in the ljacklm.h header.
+
+Refer to the INSTALL file for library requirements, build and installation
+instructions.
+
+Function execution times are comparable to one ones documented in section 4.x in
+the U12 User's Guide.
+
+Note to Mac OS X users:
+
+The libusb_get_device_list libusb call tends to be slow, causing 900+ ms
+overhead when a device needs to be found and opened over USB.  This overhead
+will be seen in your program's first libljacklm function call that communicates
+with a U12.  Subsequent function calls to the U12 in the program  will be the
+standard 20 ms execution time unless an error occurs.
+
+
+Contents of this package:
+
+The libljacklm directory contains the following:
+   * The libljacklm library source and header files, ljacklm.c and
+     ljacklm.h, and the Makefile for Linux and Mac OS X.
+
+The examples directory contains the following:
+   * This directory contains U12 code examples written in C.  The examples use 
+     the ljacklm header file installed in the /usr/local/include directory and
+     the ljacklm library installed in the /usr/local/lib directory.  The
+     applications created from the code run in a terminal.  
+
+
+The INSTALL file provides requirements and installation instructions for the
+liblabjackusb library, along with instructions on building the examples.
