"""Push the current tree to try, with the specified syntax.
Build options, platforms and regression tests may be selected
using the usual try options (-b, -p and -u respectively). In
addition, tests in a given directory may be automatically
selected by passing that directory as a positional argument to the
command. For example:
mach try -b d -p linux64 dom testing/web-platform/tests/dom
would schedule a try run for linux64 debug consisting of all
tests under dom/ and testing/web-platform/tests/dom.
Test selection using positional arguments is available for
mochitests, reftests, xpcshell tests and web-platform-tests.
Tests may be also filtered by passing --tag to the command,
which will run only tests marked as having the specified
tags e.g.
mach try -b d -p win64 --tag media
would run all tests tagged 'media' on Windows 64.
If both positional arguments or tags and -u are supplied, the
suites in -u will be run in full. Where tests are selected by
positional argument they will be run in a single chunk.
If no build option is selected, both debug and opt will be
scheduled. If no platform is selected a default is taken from
the AUTOTRY_PLATFORM_HINT environment variable, if set.
The command requires either its own mercurial extension ("push-to-try",
installable from mach mercurial-setup) or a git repo using git-cinnabar
(available at https://github.com/glandium/git-cinnabar).
