I am looking at making a custom content processor that needs to work the following way:

One file is loaded, the processing will identify several other files need (like a model needs textures) and it needs to write them to the content folder as well, but they need to be processed by the content pipeline as well.

for example:
load in: my file that references files a.txt and b.bmp
save out: my exported file, straight copy of a.txt and processed copies of b.bmp

how do I invoke the content processor to handle files within itself? or, is there a better way to do all this?
