Created page with "Pavel pointed ------------- One thing to do: LINK pie/parasite.built-in.o GEN pie/parasite.built-in.bin.o GEN pie/parasite.built-in.bin GEN pie/par..."

New page

One thing to do:

LINK pie/parasite.built-in.o
GEN pie/parasite.built-in.bin.o
GEN pie/parasite.built-in.bin
GEN pie/parasite-blob.h

LINK pie/restorer.built-in.o
GEN pie/restorer.built-in.bin.o
GEN pie/restorer.built-in.bin
GEN pie/restorer-blob.h

need a doc (on wiki I suppose) explaining why we need 4 files
for each -- parasite and restorer blobs.
