Main changes between MegaWave2 versions 1.x and versions 2.x

This guide is intended to be the User's Guide of MegaWave2 versions 2.x and it should not be used with former versions 1.x (check the version number with mwvers). For those of you who were familiar with MegaWave2 versions 1.x, I give below a short list of the most important changes between versions 1.x and version 2.00. To get an updated list of all changes, please read the file CHANGES in the distribution package.

• The Registration procedure to get a free license does no longer exists : with versions 2.x you do not have any registration form to send.
• The sources of MegaWave2 kernel (preprocessor and libraries) are given. Therefore, you are now able to modify the kernel, for example to adapt it on a new machine architecture.
• In return, the kernel binaries are no longer distributed : the local MegaWave2 administrator has to compile the kernel by himself.
• MegaWave2 has been adapted for Linux on i386.
• Effort has been done to offer more modules with associated demos, and former modules have been fully checked (some of them may see their name changed). The src directory has been deeply reorganized.
• The doc directory structure has changed : see Section 7.
• The data directory structure has changed, together with the search path convention. In short, a PUBLIC subdirectory has been created where all public data not specifically associated to some modules have to be put. To resolve an input filename, a module now searches inside all subdirectories of data (See Volume 2 ``MegaWave2 System Library'').
