;
; |> How to use <|
; To associate a file with an application so you can double-click it in explorer, use
; the APP_ASSOCIATE macro like this:
;
;   Example:
;   !insertmacro APP_ASSOCIATE "txt" "myapp.textfile" "text/plain" \
; "Description of txt files" "$INSTDIR\myapp.exe,0" "Open with myapp" \ 
; "$INSTDIR\myapp.exe $\"%1$\""
;
; Never insert the APP_ASSOCIATE macro multiple times, it is only ment
; to associate an application with a single file and using the
; the "open" verb as default. To add more verbs (actions) to a file
; use the APP_ASSOCIATE_ADDVERB macro.
;
;   Example:
;   !insertmacro APP_ASSOCIATE_ADDVERB "myapp.textfile" "edit" "text/plain" \
; "Edit with myapp" "$INSTDIR\myapp.exe /edit $\"%1$\""
;
; To have access to more options when registering the file association use the
; APP_ASSOCIATE_EX macro. Here you can specify the verb and what verb is to be the
; standard action (default verb). 
;
; And finally: To remove the association from the registry use the APP_UNASSOCIATE
; macro. Here is another example just to wrap it up:
;   !insertmacro APP_UNASSOCIATE "txt" "myapp.textfile"
;
; |> Note <|
; When defining your file class string always use the short form of your application title
; then a period (dot) and the type of file. This keeps the file class sort of unique.
;   Examples:
;   Winamp.File
;   Winamp.Playlist
;   NSIS.Script
;   Photoshop.JPEGFile
;
; |> Tech info <|
; The registry key layout for a file association is:
;HKEY_LOCAL_MACHINE
;    Software
;        Classes
;            .mp3
;                (default)=Winamp.File
;            Winamp.File
;                (default)=Winamp Media File
;                DefaultIcon
;                    (default)=c:\program files\winamp\winamp.exe,1
;                    shell
;                        Play=&Play in Winamp
;                            command
;                                (default)="c:\program files\winamp\winamp.exe" "%1$"
;                        Open
;                            command     
;                                (default)="c:\program files\winamp\winamp.exe" "%1$"
;                        ListBookmark
;                            (default)=Add to Winamp's &Bookmark list
;                            command
;                                (default)="c:\program files\winamp\winamp.exe"/BOOKMARK "%1$"
;                        Enqueue
;                            (default)=&Enqueue in Winamp
;                            command
;                                (default)="c:\program files\winamp\winamp.exe$"/ADD "%1$"
