The important facts:
* The module does not modify in any way the already existing SDL installation on your system.
* If you reinstall SDL libs on your system you do not need to reinstall Alien::SDL (providing that you use the same directory for the new installation).
* The prebuild binaries and/or binaries built from sources are always installed into perl module's 'share' directory.
* If you use prebuild binaries and/or binaries built from sources it happens that some of the dynamic libraries (*.so, *.dll) will not automaticly loadable as they will be stored somewhere under perl module's 'share' directory. To handle this scenario Alien::SDL offers some special functionality (see below).
