About:
Provides a set of functions to identify, validate and spawn weapons/melees.

Features:
- Support SourceMod 1.7, 1.11 Transitional Syntax.
- A lot of weapons/melees functions.
- Provides weapons/melees data: ID, names, models etc.

API structure:
Since the weapon_melee class contains its own melees the code has been logically divided into two parts: WEAPON and MELEE.
Both parts have functions to check for garbage value and identify their type of weapon.
The ITEM struct is needed to determine to which type (WEAPON / MELEE) an entity or weapon name belongs.

Usages:
Use L4D2Wep_Identify, L4D2Wep_NameToIDEx for WEAPON and L4D2Wep_IdentifyMelee, L4D2Wep_MeleeNameToID functions for MELEE to identify their ID by entity or class name.
If you want the code work for both types (ITEMS) use L4D2Wep_IdentifyItemByName, L4D2Wep_IdentifyItemByEnt functions to identify (See example).

When you got an WEAPON / MELEE / ITEM ID you can do following things:
- Filter weapon/melee entities.
- Grab info about: model, weapon name, weapon slot index, check for spawn class
- Create any weapons as weapon_ or _spawn class (Fixed pos/angles)
- Create any melees as weapon_melee or weapon_melee_spawn class (Fixed pos/angles)
- Give a weapon/melee to player (based on give cmd)
- Sets a weapon max ammo (based on convars)
- Sets a weapon max ammo to player (based on offsets)

Note:
l4d2_weapons does not provide a way to unlock weapons, for this goal you may use any known plugins or extensions. However, if you unlock any vanilla weapons like a knife the l4d2_weapons will detect it and support.
If you want to add custom weapons support to l4d2_weapons look at line custom melee for example.

Examples:
l4d2_weapons_test.sp plugin provides examples of how this API can be used.
