Include to Wekan packages directory contents, so that meteor command would build all directly.
This also simplifies build scripts.
Thanks to xet7 !

What you see below is slightly messy, but it's what I've managed to +cobble together to illustrate the differences between markdown engines, and +why, if there ever is a markdown specification, it has to be absolutely +thorough. There are a lot more of these little differences I have documented +elsewhere. I know I will find them lingering on my disk one day, but until +then, I'll continue to add whatever strange nonsensical things I find. + +Some of these examples may only mention a particular engine compared to marked. +However, the examples with markdown.pl could easily be swapped out for +discount, upskirt, or markdown.js, and you would very easily see even more +inconsistencies. + +A lot of this was written when I was very unsatisfied with the inconsistencies +between markdown engines. Please excuse the frustration noticeable in my +writing. + +## Examples of markdown's "stupid" list parsing + +``` +$ markdown.pl + + * item1 + + * item2 + + text +^D +<ul> +<li><p>item1</p> + +<ul> +<li>item2</li> +</ul> + +<p><p>text</p></li> +</ul></p> +``` + + +``` +$ marked + * item1 + + * item2 + + text +^D +<ul> +<li><p>item1</p> +<ul> +<li>item2</li> +</ul> +<p>text</p> +</li> +</ul> +``` + +Which looks correct to you? + +- - - + +``` +$ markdown.pl +* hello + > world +^D +<p><ul> +<li>hello</p> + +<blockquote> + <p>world</li> +</ul></p> +</blockquote> +``` + +``` +$ marked +* hello + > world +^D +<ul> +<li>hello<blockquote> +<p>world</p> +</blockquote> +</li> +</ul> +``` + +Again, which looks correct to you? + +- - - + +EXAMPLE: + +``` +$ markdown.pl +* hello + * world + * hi + code +^D +<ul> +<li>hello +<ul> +<li>world</li> +<li>hi + code</li> +</ul></li> +</ul> +``` + +The code isn't a code block even though it's after the bullet margin. I know, +lets give it two more spaces, effectively making it 8 spaces past the bullet. + +``` +$ markdown.pl +* hello + * world + * hi + code +^D +<ul> +<li>hello +<ul> +<li>world</li> +<li>hi + code</li> +</ul></li> +</ul> +``` + +And, it's still not a code block. Did you also notice that the 3rd item isn't +even its own list? Markdown screws that up too because of its indentation +unaware parsing. + +- - - + +Let's look at some more examples of markdown's list parsing: + +``` +$ markdown.pl + + * item1 + + * item2 + + text +^D +<ul> +<li><p>item1</p> + +<ul> +<li>item2</li> +</ul> + +<p><p>text</p></li> +</ul></p> +``` + +Misnested tags. + + +``` +$ marked + * item1 + + * item2 + + text +^D +<ul> +<li><p>item1</p> +<ul> +<li>item2</li> +</ul> +<p>text</p> +</li> +</ul> +``` + +Which looks correct to you? + +- - - + +``` +$ markdown.pl +* hello + > world +^D +<p><ul> +<li>hello</p> + +<blockquote> + <p>world</li> +</ul></p> +</blockquote> +``` + +More misnested tags. + + +``` +$ marked +* hello + > world +^D +<ul> +<li>hello<blockquote> +<p>world</p> +</blockquote> +</li> +</ul> +``` + +Again, which looks correct to you? + +- - - + +# Why quality matters - Part 2 + +``` bash +$ markdown.pl +* hello + > world +^D +<p><ul> +<li>hello</p> + +<blockquote> + <p>world</li> +</ul></p> +</blockquote> +``` + +``` bash +$ sundown # upskirt +* hello + > world +^D +<ul> +<li>hello +> world</li> +</ul> +``` + +``` bash +$ marked +* hello + > world +^D +<ul><li>hello <blockquote><p>world</p></blockquote></li></ul> +``` + +Which looks correct to you? + +- - - + +See: https://github.com/evilstreak/markdown-js/issues/23 + +``` bash +$ markdown.pl # upskirt/markdown.js/discount +* hello + var a = 1; +* world +^D +<ul> +<li>hello +var a = 1;</li> +<li>world</li> +</ul> +``` + +``` bash +$ marked +* hello + var a = 1; +* world +^D +<ul><li>hello +<pre>code>var a = 1;</code></pre></li> +<li>world</li></ul> +``` + +Which looks more reasonable?
