bjam template question

I'm trying to use the template target facility as described in
http://www.boost.org/tools/build/v1/build_system.htm and am having
difficluties.

Specifically the document indicates that the syntax is:

target-type name : sources
[ : requirements [ : default-BUILD ] ] ;

which doesn't seem to work for me. Looking to the build/Jamfile for
boost.test I find syntax such as the following:

template boost_test_lib
## sources ##
:
## requirements ##
## default build ##
: <threading>single/multi <runtime-link>static/dynamic
;
lib boost_prg_exec_monitor : <template>boost_test_lib
../src/$(PRG_EXEC_MON_SOURCES).cpp ;

Note the absence of the colon (":") character before ##sources. At the very
least it seems that that the documentation is out of sync with the
definition of template rule.

If I locate to the test/build directory and invoke bjam I get:

$ bjam -d5 -sTOOLS=vc-7_1 debug >bjam.log
$ tail bjam.log

make -- debug
time -- debug: missing

...found 1 target...
...can't find 1 target...
$

That is, it doesn't seem to work either.

Adjusting my Jamfile in accordance with example illustrated by
boost.test/build fails to make my build function.

Anyone is free to offer advice.
