[Tinyos-help] Regarding .extra in make system

[Jatindera Walia]

Hi,

I created the required folders in the contrib such as
school
     apps
     tos
     support
           make

I did put an xyz.extra file in the make folder and modified the
TOS_MAKEPATH but the system is not picking it up. If I put the CFLAGS
+= ... directly in the application Makefile, everything works fine. Am
I missing something?

Is there any documentation on .extra (besides the one on yamp platfom)?

Thanks
Jay
