Support DESTDIR for the main makefile's install targets.
Add Objective-C++ extension to supported file types
Merge pull request #48 from pronebird/master

Allow parsing of Objective-C++ sources
@usage code blocks are prettified
don't strip multiline tag values. Allows multiline @usage blocks to work nicely
ordinary non 'method' functions of a 'class' must be respected, and not prefixed with class:
examples of syntax highlighting in function @usage blocks; 'static' member functions
pretty field can be set to 'lxsh'; github-flavoured Markdown fenced code blocks; if lxsh, can also highlight c, sh and bib
@type summary no longer dropped (#49); @type can be used with @usage (#52); CSS tweaks for prettification; nasty '<pre/>' typo squashed
Merge pull request #39 from thmo/master

Please support DESTDIR
no longer an error for @function to have modifiers (#45), although we're not yet passing it through. New @static tag for class methods
fixed issue #47; flag-style tags like @local were blowing up with description collection
tables inside 'classes' are implicitly  'static'; respect blank lines even if not using markdown; fall back to bundled markdown.lua if not found elsewhere
modules returning a single function are supported, see tests/styles/func.lua. Parameters may have subfields, see tests/styles/subparams.lua
issue #57: [opt=default] support - see tests/styles/four.lua
merging trailing [opt] as [optchain]s. Trying to solve 'self' references in modules
fixed opt bug and weird issue when section title clashes with standard section names
module at-references now working! No-contents warning fixed
using parameters which were List method names caused chaos
bump version to 1.3.8 in usage; ignore empty docstrings (Dirk bug)
