Tangle-MD (or, Doctor Tangles) extracts source code from a literate Markdown "web" file.
Right now, this is a very preliminary version which just looks for all code fences with a language, then extracts their contents.
If you want to avoid inclusion, you could add an asterisk to the language name, e.g.,
```sml*
(* example code which won't be extracted by Doctor Tangles *)
```
Right now, it blindly takes everything, including code fences describing different languages. Obviously this is not ready for "prime time", but we're getting there...

There are a few supported metadata fields supported:
examplewill toggle a codefenced block as an "example", i.e., not included for export as sourcecode --- this is the same as adding a*suffix to the language name.file = filenamewill export the current codefenced environment (and all future codefenced environments) to the file "filename". When another codefenced block is encountered with anotherfile = different_filename, the output will be redirected. If later a codefenced environment hasfile = filename, then the code chunks are appended to the code chunks which will be directed towards file "filename".
A codefence block has its first line be ```language {metadata-field-1=value-1, ...}. Most Markdown engines will
disregard this, or (at most) use it for syntax highlighting.
This is part of a larger ecosystem of tools. For example, I intend to
use it in conjunction with md.
The unit tests require the
sml-xunit library.
You may have to update the tests.mlb file to point to
the correct location of sml-xunit/xunit.mlb.
