Now just replace all of the calls to the raw WinAPI (in our case, ShellExecuteA) with our new manually imported oShellExecuteA function pointer. Format & commit your changes, and open a PR and I'll merge your changes. Thanks!
## Lib: Error Handling
Error handling in Laika is done via the 'core/lerror.h' header library. It's a small and simple error handling solution written for laika, however can be stripped and used as a simple error handling library. Error handling in Laika is used similarly to other languages, implementing a try & catch block and is achieved using setjmp(). The LAIKA_ERROR(...) is used to throw errors.

## Lib: Packet Handlers
Laika has a simple binary protocol & a small backend (see `lib/src/lpeer.c`) to handle packets to/from peers. `lib/include/net/lpacket.h` includes descriptions for each packet type. For an example of proper packet handler definitions see `bot/src/bot.c`. It boils down to passing a sLaika_peerPacketInfo table to laikaS_newPeer. To add packet handlers to the bot, add your handler info to laikaB_pktTbl in `bot/src/bot.c`. To add packet handlers to the shell, add your handler info to shellC_pktTbl in `shell/src/sclient.c`. For adding packet handlers to cnc, make sure you add them to the corresponding table in `cnc/src/cnc.c`, laikaC_botPktTbl for packets being received from a bot peer, laikaC_authPktTbl for packets being received from an auth peer (shell), or DEFAULT_PKT_TBL if it's received by all peer types (things like handshakes, keep-alive, etc.)

## Lib: Task Service
Tasks can be scheduled on a delta-period (call X function every approximate N seconds). laikaT_pollTasks() is used to check & run any currently queued tasks. This is useful for sending keep-alive packets, polling shell pipes, or other repeatably scheduled tasks. Most laikaT_pollTasks() calls are done in the peerHandler for each client/server.

Laika has a tiny VM for decrypting sensitive information. For details on the ISA read `lib/include/core/lvm.h`, for information on how to use them read `lib/include/core/lbox.h`. Feel free to write your own boxes and contribute them :D
## Bot: Platform-specific backends
`bot/win` and `bot/lin` include code for platform-specific code that can't be quickly "ifdef"d away. These mainly include stuff like persistence or opening pseudo-ttys.
