+
+This directory is intended for project header files.
+
+A header file is a file containing C declarations and macro definitions
+to be shared between several project source files. You request the use of a
+header file in your project source file (C, C++, etc) located in `src` folder
+by including it, with the C preprocessing directive `#include'.
+
+```src/main.c
+
+#include "header.h"
+
+int main (void)
+{
+ ...
+}
+```
+
+Including a header file produces the same results as copying the header file
+into each source file that needs it. Such copying would be time-consuming
+and error-prone. With a header file, the related declarations appear
+in only one place. If they need to be changed, they can be changed in one
+place, and programs that include the header file will automatically use the
+new version when next recompiled. The header file eliminates the labor of
+finding and changing all the copies as well as the risk that a failure to
+find one copy will result in inconsistencies within a program.
+
+In C, the usual convention is to give header files names that end with `.h'.
+It is most portable to use only letters, digits, dashes, and underscores in
+header file names, and at most one dot.
+

+/* This driver uses the Adafruit unified sensor library (Adafruit_Sensor),
+   which provides a common 'type' for sensor data and some helper functions.
+   
+   To use this driver you will also need to download the Adafruit_Sensor
+   library and include it in your libraries folder.
+
+   You should also assign a unique ID to this sensor for use with
+   the Adafruit Sensor API so that you can identify this particular
+   sensor in any data logs, etc.  To assign a unique ID, simply
+   provide an appropriate value in the constructor below (12345
+   is used by default in this example).
+   
+   Connections
+   ===========
+   Connect SCL to analog 5
+   Connect SDA to analog 4
+   Connect VDD to 3.3V DC
+   Connect GROUND to common ground
+    
+   History
+   =======
+   2013/JUN/17  - Updated altitude calculations (KTOWN)
+   2013/FEB/13  - First version (KTOWN)
