+Standard markdown
+=================
+
+Standard markdown is a specification of markdown syntax, together
+with implementations (`stmd`) in C and javascript.
+
+The C implementation provides both a library and a standalone program
+that converts markdown to HTML.  It is written in standard C99 and has
+no library dependencies.  (However, if you check it out from the
+repository, you'll need `re2c` to generate `scanners.c` from
+`scanners.re`.  This is only a build dependency for developers, since
+`scanners.c` can be provided in a released source tarball.)
+
+The javascript implementation is a single javascript file
+that can be linked to an HTML page.  A standalone version (using
+`node.js`) is also provided (`js/markdown`), and there is a
+"dingus" for playing with it interactively.  (`make dingus` will start
+this.)
+
+The spec contains over 400 embedded examples which serve as
+conformance tests.  To run the tests for `stmd`, do `make test`.
+To run them for another markdown program, say `myprog`,
+do `make test PROG=myprog`.  To run the tests for `stmd.js`,
+do `make testjs`.
+
+The source of the spec is `spec.txt`.  This is basically a markdown
+file, with code examples written in a shorthand form:
+
+    .
+    markdown source
+    .
+    expected HTML output
+    .
+
+To build an HTML version of the spec, do `make spec.html`.
+To build a PDF version, do `make spec.pdf`.  Both these commands
+require that pandoc is installed, and creating a PDF requires
+a latex installation.
