               Mapbase - Source 2013
	https://github.com/mapbase-source/source-sdk-2013

//===================================================================================================================================================

This repository contains code from Mapbase, a modification of the Source 2013 SDK which serves as a combined package
of general-purpose improvements, fixes, and utility features for mods.

Mapbase's main content in this repository may include:

- 80+ custom entities (new logic entities, filters, etc.)
- Hundreds of Inputs/Outputs/KeyValues additions and modifications
- Custom SDK_ shaders with improvements adapted from Alien Swarm SDK code, including projected texture fixes and radial fog
- Custom VScript implementation based on public Squirrel API and Alien Swarm SDK interfaces/descriptions
- Additional gameplay control for Half-Life 2 mods, including grenade features for more NPCs and singleplayer respawning
- More map-specific capabilities for maps unable to branch into their own mods, e.g. MP mods or map compilations
- View rendering changes for drawing 3D skyboxes and RT-based entities
- Countless other fixes and improvements

//===================================================================================================================================================

Mapbase is an open-source project and its contents can be distributed and used at the discretion of its users. However, this project represents many parts of
the Source modding community packaged into a whole, so credit is taken very seriously.

	Up-to-date information about Mapbase content usage and credit are addressed in this article on Mapbase's wiki:

//===================================================================================================================================================

>>>>>>>> EXTERNAL CONTENT USED IN MAPBASE <<<<<<<<

The Mapbase project is a combination of original code from its creators, code contributed by other Source modders, and code borrowed from open-source articles
and repositories (especially ones which are specifically published as free source code). One of Mapbase's goals is to make the most popular fixes and the most obscure
or complicated code changes accessible and easy to use for level designers and other kinds of Source modders who would otherwise have no idea how to implement them.

*** DISCLAIMER: Mapbase has a strict no-leak-content policy and only allows content created directly by contributors or content originating from open-source repositories.
If you believe any content in Mapbase originates from any leak or unauthorized source (from Valve or otherwise), please contact Blixibon immediately.
Mapbase is intended to be usable by everyone, including licensed Source projects and Steam mods. ***

-- The Alien Swarm SDK was used to backport features and code from newer branches of Source into a Source 2013/Half-Life 2 environment.
-- Mapbase also implements some of Tony Sergi's code changes from the Source 2007 SDK codebase. Both SDKs are publicly distributed by Valve and are available on Steam.

Some of the features backported from the Alien Swarm SDK (e.g. game instructor, particle rain) require assets from later versions of Source in order to work properly.
The required assets have been backported from Alien Swarm and Left 4 Dead for the release build. They are not available in the code repository.
