3.) Installation instructions

There aren't any difficulties with current distribution other than add
\Source\Lib directory to library or search path. (...or you can simply put all

čiže v menu IDE: Tools -> Options... -> Library -> Library Path..

Či je to dobra voľba na posielanie mailu s prílohou neviem posúdiť...
