First of all, install the sources as told in Getting the sources of OOo (RC3) for Debian. Next, go edit debian/rules to see where apply.pl is called and with which arguments. You can probably see this: $(TOOLS_DIR)/patches/apply.pl $(TOOLS_DIR)/patches/$(PATCH_DIR) $(BUILD_DIR) –distro=Debian -f $PATCH_DIR is taken from debian/scripts/vars, where you can see something like: # Directory of patch apply file PATCH_DIR=OOO_1_1_RC3 It means you should have a look to ooo-build/patches/OOO_1_1_RC3/apply to know which patches are applied, depending on the --distro= option, off course. Patches are taken from the $PATCHPATH directory, which you can read in the apply file.You can now play with the sections [ Ximian, Debian ], or [ Ximian ], or … you get the point.
The build system will copy each patch into applied_patches at a time just after applying it, prepending a number to its name.
