With Ubuntu 16.04, the tcmalloc-minimal4 package doesn't provide a version of tcmalloc that satisfies trck. However, the version of tcmalloc installed via the libgoogle-perftools-dev does.

Thus, trck may need to be updated to be able to use the version specified in the install instructions OR the perftools package should be referenced in the install instructions.

It would would nice to be able to specify "-h" or "--help" to binaries produced by trck to get info on available arguments.

I've tried the following basic query:

main ->
    receive
        campaign_id = "1234" -> yield $counter
        * -> repeat

$ ./bin/trck query.tr data.tdb

I'm quite sure that the filter works:

$ tdb dump --filter='campaign_id=1234' -i data.tdb | wc -l
     436

I'm using the following:

• OSX
• Python 2.7 with ply installed
• traildb installed from brew
• judy 1.0.5
• trck manually compiled

What am I doing wrong?

Would be nice to have Travis CI setup to help ensure the code isn't broken when new PRs are submitted.
