ffd85bcc3e Fixes a long-standing bug in import under Python 3.3 and later.
Our MetaImporter was being inserted at the end of sys.meta_path.
For Python prior to 3.3, this was fine since sys.meta_path
was empty by default. As of the completion of PEP 302 in Py3.3 and
later, there are several importers registered by default. One of
these was trying (and failing) to import simple Hy modules,
resulting in a failure to import anything inside __init__.hy.

This change simply inserts the Hy-specific importer at the front
of the list.

This was noted in issue #620 (great catch @algernon)

774aad2ca8 defmain macro; handles the whole if __name__ == __main__ / main function dance
Example:

  (defmain [&rest args]
    (print "now we're having a fun time!")
    (print args))

Which outputs:

  $ hy test.hy
  now we're having a fun time!
  (['test.hy'],)

Includes documentation and tests.

875d5f2ff5 Rewrite the bootstrap macros in hy
This gets rid of the dichotomy between bootstrap.py and macros.hy,
by making both files hy modules.

I added some error checking to make the macros more resilient. The
biggest (user-visible) change is the change in cond, which now only
accepts lists as arguments. Tests updated accordingly.

Closes: #176 (whoops, no more bootstrap)

df7bb1d29a Provide bin scripts for both Windows and *nix
Summary: This update does away with the scripts in bin and changes
setup.py to use entry_points in cmdline.py for the scripts 'hy' and
'hyc'.

This fixes installing and running on Windows.

The tests are updated to run the 'hy' script produced by setup.py
and not from bin/hy. This is more correct and makes the tox tests
run on both Window and *nix.

For running hy or nosetests directly in the source tree, you do have
to run 'python setup.py develop' first. But since tox runs and builds
dists, all tox tests pass on all platforms.

Also, since there is no built-in readline on Windows, the setup.py
only on Windows requires 'pyreadline' as a replacement.

Switched from optparse to argparse in cmdline.py

Instead of trying to manually separate args meant for
hy from args meant for a hy script, this switches from
optparse to argparse for the CLI.

argparse automatically peels out args meant for hy and leaves
the rest, including the user hy script in options.args.

This fixes the issue @paultag found running "hy foo" where
foo is not a real file. Also added a test that makes sure
trying to run a non-existent script exits instead of dropping
the user into the REPL.

Added argparse as setup.py resource (and removed from tox.ini) as well as removed uses of deprecated setf
