From ec46692cf5c4d5e22950bc8e7d14cb0ec327fb87 Mon Sep 17 00:00:00 2001 From: Waylan Limberg Date: Wed, 7 Mar 2012 09:35:40 -0500 Subject: Rename docs/*.md => docs/*.txt The documentation uses features of Python-Markdown that are not supported on GitHub and it's better to get a source view of the docs anyway. For example, that way comments and bug reports can reference a specific line of a file. Of course, it makes sense for Github to render the README, so that is left with the `.md` file extension. --- docs/test_suite.md | 133 ----------------------------------------------------- 1 file changed, 133 deletions(-) delete mode 100644 docs/test_suite.md (limited to 'docs/test_suite.md') diff --git a/docs/test_suite.md b/docs/test_suite.md deleted file mode 100644 index cf9353c..0000000 --- a/docs/test_suite.md +++ /dev/null @@ -1,133 +0,0 @@ -title: Test Suite -prev_title: Extension API -prev_url: extensions/api.html - -# Test Suite - -Python-Markdown comes with a test suite which uses the [Nose][] testing -framework.The test suite primarily serves to ensure that new bugs are not -introduced as existing bugs are patched or new features are added.

The txt file contains a snippet of Markdown source text -formated for a specific syntax feature and the html file contains the expected -HTML output of that snippet.
