Difficult to find gmx select documentation
I find it difficult to find the gmx select syntax. I end up googling it and wind up here: http://www.gromacs.org/Documentation/Gromacs_Utilities/g_select where I read that
g_select -select 'help all'
should give me the docs. On my (master-based) gmx doing
gmx select -select 'help all'
gives a syntax error.
To get to the docs I need a tpr and do 'gmx select -s topol.tpr' and then 'help' and then e.g.'help syntax'. It would be much better if 1) I get info about how to reach the docs directly from 'gmx select -h' and 2) if I can go through the docs without providing any input.
Make it easier to find selection help

The "problem" (if it can be called that) is that the selection mechanism is gradually being introduced into multiple tools; the help info is no longer unique to gmx select, which in old versions as g_select, was the only tool that used the selection syntax. Now, others (e.g. gmx distance) use it, too. So what you want is
gmx help selections
which can then be used to find syntax, examples, etc. Much of the information on the wiki is getting outdated, and I haven't had time to keep up with that as I once did, but of course others can add to it with new information that they learn :)
