Script to scan .sci and .sce files and displays percentage of lines
having function disp() and/or printf(). Run the script using:
./display_density.py
It should print filenames with percentage which is equal-to or exceeds LIMIT.
The default log file(density.log) has detail information of line counts
Usage:
1. Unzip the .zip file(s)
2. Set the directory to scan, by default the script will scan all directories in
present directory
3. Set the percentage limit in variable PERCENTAGE_LIMIT
4. Optionally you can set the log file name
