makefile: @ preceding command

[paolopiace]

I was not able to retrieve info about the following.

I have a makefile with this rule:

test: main.cpp
@g++ -lcurl main.cpp -o test.out -g

Question(s):
- What is the '@' symbol preceding g++? (I've never seen it...)
- What does it mean/do?
- Is it a syntax restricted to makefile or is a general syntax for shell commands?

Thanks...

Actually, I found it here:

I don't see how "Automatic-Variables" is the answer to my question.
