Using CSS textures in HL2?

[Bilko]

I know this may have been said already but I can't seem to find it by searching.

I want to put all of the CSS textures in HL2 so I can use them in my HL2 maps. Is this possible?

Also, if I compile the map with the CS textures and give the map to someone, will they be able to load those CS textures.

Thanks for the help!
