Run ./build.sh APP to distribute needed files to package's root directory.
After that, go back to .. and run ./configure and make, then start or
install the application.

Before compilation, fetch the data files by using build/pkget.sh script if you
haven't done so yet. Run this in package root directory (where the configure
script is):

 $ ./build/pkget.sh

Example steps for compilation (in this directory):

 $ ./build.sh fossmixer
 $ cd ..

Next, to try app without installing it:

 $ ./configure --prefix=`pwd` \
               --with-libiconv=/where/is/your/libiconv
 $ make
 $ ./fossmixer

Or alternatively, to install app:

 $ ./configure --prefix=/install/root/for/app \
               --with-libiconv=/where/is/your/libiconv
 $ make
 $ make install
 $ /install/root/for/app/bin/fossmixer
