yes, the idea was to move the functionality of the gdal utilities to 
GDAL core in order to have it available directly when using the library 
and thus to facilitate their usage from "external" programs. The 
functionality should be usable with the GDALRunUtility() function. This 
would avoid e.g. a system call to a tool or code duplication which is 
currently needed in order to create a GDAL vrt for example.

It is not intended to remove the GDAL tools, but they would have to be 
reworked to just provide the parameter interface and then to call 
GDALRunUtility() themselves. The idea to have a GDALRunUtility() 
function is to have a unique entry point and common interface to all 
tool functionality.

Best regards,
Volker
