Weapon portal base
Template:Entity It's a code class in 
which is a base class for all weapons entities in Portal 1 and 2. (Which is redundant in because there's only one.)
While its classname entity goes entirely unused, it can be repurposed by maps and mods to make simple custom weapons.
If a valid weapon script named weapon_portal_base.txt is placed in the /scripts/ folder, it will use that script to define its models, ammo type, etc (this works even if the script is packed into the map). If the script allows the weapon to fire bullets, it will shoot as a low accuracy machine gun, similar to how the AR2 fires (it has no secondary fire though).
If its ammo type is valid, it will do damage like any other weapon, allowing for the creation of a fully custom machine gun without any new weapon code.
As far as is known there is no ammo type in
If the script is one that doesn't shoot bullets (for example, if the gravity gun script is copied over), it will still act as a viewmodel and play firing animations, which is perfect for making new mechanically distinct weapons via entities like game_ui (for getting player left and right clicks) and logic_measure_movement (to move entities to the players eye position, for spawning projectiles or other weapon effects).
If the player doesn't have an item_suit (which is always the case in Portal 2, as it doesn't exist there), the command use weapon_portal_base can be used to switch to this weapon, and use weapon_portalgun can be used to switch back to the portal gun.
Create a weapon_portal_base.txt and put it in the scripts/ folder to create a custom weapon.
Bug:Going through a trigger_portal_cleanser after the player has placed portals will show the portal gun's fizzle animation, even if the player is not holding the portal gun. This can be worked around by setting up a trigger_multiple and a game_ui to hide the player's held weapon while they walk through the fizzler. [todo tested in ?]FGD Code
