mimeapps - finding association between MIME types and applications

[FreeSlave via Digitalmars-d-announce]

mimeapps is a library for detection of which applications can be 
used to open files of given MIME type.

Note: this is essential only for systems that follow Freedesktop 
specifications, i.e. Linux, BSD and some others. MS Windows and 
OS X have their own file type associations systems.
