Tobias Schlitt has a new note posted over on his weblog today about the implementation of trackbacks in the PEAR website.

So, what does this exactly mean? I think, everyone reading blogs should know, what a trackback is. If not, here is a little abstract on that from the Movabletype website (where more detailed information can be found): In a nutshell, TrackBack was designed to provide a method of notification between websites: it is a method of person A saying to person B, "This is something you may be interested in." To do that, person A sends a TrackBack ping to person B.

[...] That so far to the system of trackbacks. But what does all that have to do with PEARWeb and PEAR packages? PEAR (in some way) lacks documentation. So, if someone writes a blog entry on a PEAR package he can send a trackback ping to indicate, that he created another piece of documentation. A link will automatically be placed on the package info page of the related PEAR package.

I think that this is a great little addition to the PEAR website. Not only can it help with the documentation (as he mentions), but it can also help to foster more growth/usage in the PEAR realm through a clearer promotion of the packages...
