Proper syntax of 'project' rule

The documentation of 'project' is not very clear. There are separate
examples of 'requirements' and 'usage-requirements' but no example of
using both together.

Is the syntax:

project lib : requirements ... : usage-requirements ...

or:

project lib : requirements ... usage-requirements ...

What I mean is do I need the colon to separate 'requirements' from
'usage-requirements' ?

I tried both.

1) Without the colon, I get an error.

2) with the colon, the dependent target on this library doesn't seem
to get the usage-requirements. It should get -I"c:/icc/include" added
to its compiler options, but it doesn't.

Here's my Jamfile:
#===============================
project /lib-nvm : 
requirements <include>c:/icc/include
:
usage-requirements <include>c:/icc/include
;

lib nvm : nvm.c ;
#==================================

Thanks!
