Hi, everyone,

I use FeynCalc8.2.0 in mathematica 8.

I want to define some functions in the context test`.
In the definitions of those functions, I want to
use some functions in FeynCalc. Besides, functions
in test` and functions in FeynCalc` can be used together.

However, BeginPackage["test`", "HighEnergyPhysics`FeynCalc`"]
leads to $ContextPath {test`,HighEnergyPhysics`FeynCalc`,System`},
functions such as GA, SP etc are undefined in this $ContextPath.

If we load FeynCalc in test`Private`,i.e.,
BeginPackage["test`"]
...
Begin["`Private`"]
Needs["HighEnergyPhysics`FeynCalc`"]
...
...
EndPackage[]
Then in the context text`, GA etc can be used.
But how should we load FeynCalc outside test`?
Needs["HighEnergyPhysics`FeynCalc`"] only
add "HighEnergyPhysics`FeynCalc`" to $ContextPath!

Thanks
