+bin_to_cso_mp3
+Originally written by Exophase as "bin_to_iso_ogg"
+updated for cso/mp3 by notaz
+
+
+About
+-----
+
+This is a tool to convert cue/bin CD image to cue/cso/mp3 form, useful to use
+with emulators. It can also create ISO instead of CSO and WAV instead of MP3.
+Note that input must be .cue file, along with single .bin file.
+
+
+Easy/Windows usage
+------------------
+
+1. Download LAME from http://lame.sourceforge.net/links.php#Binaries
+   You need an archive or "LAME Bundle" with lame.exe inside. Extract lame.exe
+   to the same directory as bin_to_cso_mp3.exe
+2. Find ciso.exe . It usually comes with ISO->CSO converters, for example yacc
+   (http://yacc.pspgen.com/). Extract ciso.exe to the directory from previous
+   step.
+3. Drag the .cue file you want to convert onto bin_to_cso_mp3.exe . It should
+   pop up console window with some scrolling text, which should close by itself
+   when done. After that you should see new directory with converted files.
+
+
+Advanced usage
+--------------
+
+Just run bin_to_cso_mp3.exe from console terminal (or "command prompt") without
+any parameters to see usage.
+
+
+Linux
+-----
+
+You will need to compile bin_to_cso_mp3.c yourself using gcc:
+$ gcc bin_to_cso_mp3.c -o bin_to_cso_mp3
+
+You will also need to have lame and ciso binaries in PATH. Those can sometimes
+be installed using packet manager from the distribution, or you can compile
+them from sources:
+lame: http://lame.sourceforge.net/
+ciso: http://ciso.tenshu.fr/
