:base can be omitted? I like making deps specific but for consistency with the
other code in this file.

[Adam Rice, 2015/11/05 05:30:40]

Done, thanks.

[tyoshino (SeeGerritForStatus), 2015/11/04 08:34:07]

can we make distinction between net/base/swr_histogram_domains and
net/swr_histogram_domains more clear on this BUILD file? rename either of them a
bit?

[Adam Rice, 2015/11/05 05:30:40]

I renamed //net:swr_histogram_domains to swr_domain_matcher. The structure of
the build targets is a bit unnatural for GN, in order to make it work the same
as the GYP build.
