If you need to convert files from one markup format into another, pandoc is your swiss-army knife. Need to generate a man page from a markdown file? No problem. LaTeX to Docbook? Sure. HTML to MediaWiki? Yes, that too. Pandoc can read markdown and (subsets of) reStructuredText, textile, HTML, and LaTeX, and it can write plain text, markdown, reStructuredText, HTML, LaTeX, ConTeXt, PDF, RTF, DocBook XML, OpenDocument XML, ODT, GNU Texinfo, MediaWiki markup, textile, groff man pages, Emacs org-mode, EPUB ebooks, and S5 and Slidy HTML slide shows. PDF output (via LaTeX) is also supported with the included markdown2pdf wrapper script.

Pandoc understands a number of useful markdown syntax extensions, including document metadata (title, author, date); footnotes; tables; definition lists; superscript and subscript; strikeout; enhanced ordered lists (start number and numbering style are significant); delimited code blocks; markdown inside HTML blocks; and TeX math. Other options include “smart” punctuation, syntax highlighting, automatically generated tables of contents, and automatically generated citations (using citeproc-hs). If strict markdown compatibility is desired, all of these extensions can be turned off with a command-line flag.

Pandoc includes a Haskell library and a standalone executable. The library includes separate modules for each input and output format, so adding a new input or output format just requires adding a new module.

MarcoPolo brings context-aware computing to your portable Mac computer. It allows your computer to determine its context through gathering evidence from your environment (evidence sources), using flexible rule-based fuzzy matching to make an educated guess (rules), and then performing arbitrary actions upon changing context (actions).

MarcoPolo's concept of contexts is a generalisation of a location, and encompasses more than just where your computer is. A context might represent what you are doing, or what else is going on around you.

MarcoPolo quietly stays in the status bar at the top of your screen (right-hand side of the menu bar), from where it can be configured to your own needs.

Plain Clip is a tiny Mac OS X application which will remove formatting from text which is on the clipboard. It's designed as a face­less application (i.e.: no graphical user interface, with the excep­tion of the preferences win­dow), which makes it ideal for triggering it from a hotkey / launcher applications such as Spark or Launch­Bar. For users of such tools, Plain Clip offers a way to invoke it with a shell command, which makes it possible to emulate a “Cmd-V” / “Paste” keyboard shortcut after the clipboard’s content has been converted.

Moreover, since version 2.0 Plain Clip has offered removal of trailing whitespace and control characters such as non-breaking spaces. Plain Clip 2.1 introduced another optionally text filter: line breaks can be removed, but at the same time consecutive line breaks are retained, so that paragraphs in the text are preserved. Finally, Plain Clip 2.2 added removal of consecutive spaces and version 2.3 supports conversion to 7-bit ASCII.
