4.1 Using a Practical Project Workspace
In the course of developing and customizing software for your target, you will need to organize
various software packages and project components in a comprehensive and easy-to-use
directory structure. Table 4-1 shows a suggested directory layout you may find useful. Feel
free to modify this structure to fit your needs and requirements. When deciding where to place
components, always try to find the most intuitive layout. Also, try to keep your own code in a
directory completely separated from all the packages you will download from the Net. This will
minimize any confusion regarding the source's ownership and licensing status.
