libytnef0-dev - 2.1.2-1+b2 main

Yerase's TNEF Stream Reader allows you to decode application/ms-tnef
e-mail attachments, which are usually entitled "winmail.dat" and are
generally a file container format that is only readable by Microsoft
Outlook. Some TNEF streams also include RTF-formatted data.
.
libytnef0 is the support library that exposes these functions to other
programs. The ytnef program is the frontend for this library, so you should
probably install that (included in ytnef-tools) if you want to take advantage
of it.

These are the development headers for libytnef0.
