    Merge pull request #66 from Tieske/fix_temp
    windows environment variable TMP is deprecated, use TEMP

    added utils.executeex, which also returns output of stdout and stderr
    windows environment variable TMP is deprecated, use TEMP

    manual merge of John Schember's readonly table support
    Merge pull request #61 from user-none/isempty
    Thanks, John!
    Merge pull request #62 from CoolisTheName007/patch-2
    Transform using values as keys.
    missing locals
    Set.issempty mispelling; default ctor borked; more tests
    Transform using values as keys.
    Merge remote-tracking branch 'upstream/master' into empty
    Add function to check if an object is empty.
    Merge pull request #53 from pkazmier/master
    Added iterators to allow traversing tables in a sorted manner
    Merge pull request #60 from theypsilon/master
    base class methods invocation possible not only in method constructor _init
    Adding new class method 'base' which can be used for calling base class methods easily
    pl.class broke with classes that redefined __newindex; OrderedMap can now use normal indexing to assign keys in order
    Merge pull request #54 from CoolisTheName007/patch-1
    Typo fixed, libarary->library
    Typo fixed.
    Added tablex.sort and tablex.sortv to iterate over sorted elements
    There are times when it would be convenient to iterate over a table
    either by sorted keys or values. There is an example of this in the
    PIL book. I added the two functions to tablex module, added two test
    cases, and updated the PL manual.
    Merge pull request #51 from pkazmier/master
    Thanks!
    lapp.add_type was broken due to uninitialized table variable.
    The variable `types` was not initialized preventing `add_type` from
    appending custom types to the variable. I also added a new test to
    cover this test case in the future.
Updated devel/lua-penlight to 1.1.1.
Use ${LUA_CDIR} and ${LUA_LDIR}.
Fix shell syntax error which has been breaking all gem builds on SunOS for
the past week as per the reports on pkgsrc-bulk.  Not sure why it wasn't
showing up on other platforms, but I am assuming this is the correct fix.

LuaJIT is a Just-In-Time Compiler (JIT) for the Lua programming language.
Lua is a powerful, dynamic and light-weight programming language. It may
be embedded or used as a general-purpose, stand-alone language.
Added lang/LuaJIT2 version 2.0.2.
