Opening a file in netbeans with a different type

As it seems, since NetBeans 6.5 it is possible to open files with a different type.

In one of our C/C++-Projects we use a lot of different makefile, depending on the
target to be created
In NetBeans 6.1 there was no syntax highlighting.

Since NetBeans 6.5 on the Files Panel in the menu is a "Open As"-entry, which
lets you select the type of the file and than you get the syntax highlighting!!.

Now there is also syntax highlighting for my other makefiles.

Many thanks to the NetBeans-Team
