* Try to determine the installation directory for a software package.
* Typically used by GNU software packages.
*
* @package should be a short identifier for the package. Typically it
* is the same identifier as used for GETTEXT_PACKAGE in software
* configured accoring to GNU standards. The function first looks in
* the Windows Registry for the value #InstallationDirectory in the
* key #HKLM\Software\@package, and if that value exists and is a
* string, returns that.
*
* If @package is NULL, or the above value isn't found in the
* Registry, but @dll_name is non-NULL, it should name a DLL loaded
* into the current process. Typically that would be the name of the
* DLL calling this function, looking for its installation
* directory. The function then asks Windows what directory that DLL
* was loaded from. If that directory's last component is "bin" or
* "lib", the parent directory is returned, otherwise the directory
* itself. If that DLL isn't loaded, the function proceeds as if
* @dll_name was NULL.
*
* If both @package and @dll_name are NULL, the directory from where
* the main executable of the process was loaded is uses instead in
* the same way as above.
