Add support for compiling ASN.1 files with asn1ct.
Patch from Ruslan Babayev.

Add get-deps and delete-deps to commands info string and
bash completion script.

Add create command's template variable to bash completion.

Before we check for zip:foldl/3 make sure zip module is loaded.

one item done, another one saved

Add -c/--commands option to the bash completion script.

Implement new option -c/--commands to print available
commands and its variables.

A TODO file is always a good idea.

Comment what has to be done when the new OTP release is out
and the time is right.

escript:foldl/3 was undocumented and has been replaced with
better APIs post-R13B04. The new exported funs are officially
documented.

1.  When running the eunit command with the convention of putting
tests in "*_tests" modules, eunit would run those tests twice.  This
is because: 1) eunit:test/1 will naturally look for foo's tests both
in foo, and in foo_tests, and 2) eunit:test/1 was being folded over
all project modules.  The fix is to filter "*_tests" modules from the
list passed to eunit:test/1.

2.  When running the eunit command with cover enabled and tests in a
'test' directory, cover would error because it couldn't find the
source code for those tests.  This is because cover:analyze/3 will
only find module source in "." and "../src".  This is hard-coded in
cover :-(.  Since cover shouldn't be calculating code coverage on test
code anyway, the fix is to not fold cover:analyze/3 over
non-production code.

3.  When running the eunit command with cover enabled and a test suite
defined, cover would only attempt to calculate coverage on the the
test suite itself.  This was because only the suite was passed to
cover:analyze/3.  The fix is to fold cover:analyze/3 over all the
production code, filtering out the suite module if it is defined.

The wrapper can now be removed as I've fixed the problem in R13B04.

usage: {chmod, Mode, File}
where: Mode is an integer, as specified by the 'mode' field of the file_info record
       (see docs for file:write_file_info/2)

{file,In,Out,true} = render with mustache
{file,In,Out,false} = do not render with mustache (leave as-is)

old-form {file,In,Out} is equivalent to {file,In,Out,true}
