src is the source code for the weapons in case you ever want to modify anything,what you need is modofmods2 (basically its compilation of mods i strung together,TN,CD ect saves you trying to install everything manually)http://rapidshare.com/files/275583327/ModofMods_V_2.5.rar
HOW TO INSTALL
its simple you just go to to computer/local disk c/program files now find your postal folder and then awp folder. Now you should see animations/textures/static meshes/sounds (if you dont see sounds, copy sound folder from STP) now go to mod folder and copy and paste the animations/textures/static meshes ect.. to the awp or stp animation/textures/static meshes and so fourth!! and if you did it right, the mod should work. :]
NOTE: WEAPONS WILL ALWAYS APPEAR IN THE NEIGHBORS HOUSE!!
ALL CREDIT OF THE MOD GOES TO:
Wolveski, ALCRD, kamek, silent wrath & canada_dry
now the awp mod cheats should work and you should get loads of new weapons
