by the way , when you use this tool? I though we do not need this is you crony all computers and use message filter.

instead of that, why don't we add doc for it?

[k-okada]

doc is ok, but people who use this without knowing this is designed for the
system never reads the doc.

and why do they use this node without reading doc or code?
(so should I comment about this in the code?)

if you worry about the limited use case, we can create a new package
'jsk_test_tools' as jsk_topic_tools.

because the node exists.

[wkentaro]

because the node exists.

because the node is necessary for their system, isn't it? If so, they should read the documentation (or code).

[k-okada]

they somehow find the node and misinterpret the usage, I'm pretty sure that
someone will use this node to avoid timestamp problem in next 6 month,
believe me.

So you mean they misunderstand this as substitute for topic_tools/throttle.

I think I understand your concern, and I'd like to avoid that possibility by putting it another package. could I create a new package? (jsk_test_tools) to serve nodes for test like
jsk_tools/test_stdout.py.

[k-okada]

people who do not read document will think this is a magic node that solves
all tf problem, so crating new package did not solve, just print out BIG
warning message.

Okay.
I believe your idea that comes from experience,
and will add warning message.

Maybe that kind of people overlook the warning message, so you say BIG ;)
