Subject: Added support for a true "portable" mode: If you rename the LameXP executable to... 
X-Git-Tag: Release_400~67
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=fb707cb257df5a3e4ae961a48f01a39de47faf69;p=lamexp%2FLameXP.git

Added support for a true "portable" mode: If you rename the LameXP executable to 'LameXP-Portable.exe' it will store the configuration file in the same folder where the executable is located. This might be helpful if you put LameXP onto your USB stick and use it on different computers regularly. Important: In "portable" mode the user is responsible to make sure that write-access to LameXP folder is available!
