* example.c
*
* Calculate the sum of a given range of integer numbers. The range is
* specified by providing two integer numbers as command line argument.
* If no arguments are specified, assume the predefined range [0..9].
* Abort with an error message if the resulting number is too big to be
* stored as int variable.
*
* This program example is similar to the one found in the GCOV documentation.
* It is used to demonstrate the HTML output generated by LCOV.
*
* The program is split into 3 modules to better demonstrate the 'directory
* overview' function. There are also a lot of bloated comments inserted to
* artificially increase the source code size so that the 'source code
* overview' function makes at least a minimum of sense.
