Infernio

Basically (for certain definitions of 'basic'), the patching (on PBash, I don't really understand how it works for CBash) works like this:

The user clicks Build Patch
PatchDialog.PatchExecute is called. This is the central method.
It calls init_patchers_data, which calls initData on each patcher.
Now it differs from patcher to patcher. Some use initData to read a lot of mod file to gether information, some don't use it at all (because they don't need it).
Next, PatchExecute calls initFactories. This asks every patcher, 'hey, which record types do you actually need to read and write?'
Every patcher answers, and we make a union of the results.
Next, PatchExecute calls scanLoadMods. This loads every file in the load order, skipping all record types that no patcher wanted. Most patchers stick every record they could potentially patch into the BP at this point (you'll see why later).
This is where the BP merges mods, resolves aliases, applies Filter and IIM tags, etc.

CBash, a DLL that only loads plugin files, but does it damn quickly:

Attention all Lorebeards:

Titus Mede II is in great danger, and he needs your help to wipe the Thalmor off the face of Nirn. But to do This, he needs more towers, and a couple more towers. To help him, all he needs is for you to install this mod list containing several hundred tower-adding mods. But, you gotta be quick so that Titus Mede II can win the war or else the Thalmor will unmake all of creation.

What started out as a stupid joke on the xEdit discord has grown into a collection of more than 80 tower mods. Yes, I really did waste a day on this silly thing.
