Plugin to support importing updates from external RSS and Atom feeds into your timeline.
Uses PubSubHubbub for push feed updates; currently non-PuSH feeds cannot be subscribed.
Todo:
* set feed icon avatar for actual profiles as well as for preview
* use channel image and/or favicon for avatar?
* garbage-collect subscriptions that are no longer being used
* administrative way to kill feeds?
* functional l10n
* clean up subscription form look and workflow
* use ajax for test/preview in subscription form
* rssCloud support? (Does anything use it that doesn't support PuSH as well?)
* possibly a polling daemon to support non-PuSH feeds?
* likely problems with multiple feeds from the same site, such as category feeds on a blog
(currently each feed would publish a separate notice on a separate profile, but pointing to the same post URI.)
(could use the local URI I guess, but that's so icky!)
* problems with Atom feeds that list <link rel="alternate" href="..."/> but don't have the type
(such as http://atomgen.appspot.com/feed/5 demo feed); currently it's not recognized and we end up with the feed's master URI
* make it easier to see what you're subscribed to and unsub from things
* saner treatment of fullname/nickname?
* make use of tags/categories from feeds
* update feed profile data when it changes
* XML_Feed_Parser has major problems with category and link tags; consider replacing?

XML_Feed_Parser 1.0.3 is not currently actively maintained, and has
a nasty bug which breaks getting the feed target link from WordPress
feeds and possibly others that are RSS2-formatted but include an
<atom:link> self-link element as well.
Patch from this bug report is included:
http://pear.php.net/bugs/bug.php?id=16416
If upgrading, be sure that fix is included with the future upgrade!

<title>پروژه‌ی هاروارد، قدم دوم</title>
<link>http://editormyself.info/archives/2005/10/051012_014641.shtml</link>
<description><![CDATA[<p>اگر یادتان باشد <a href="/archives/2005/09/050906_014504.shtml">چند وقت پیش نوشتم</a> که دانشگاه هاروارد پروژه‌ای دارد با نام آواهای جهانی که در آن به وبلاگ‌های غیر انگلیسی‌زبان می‌پردازد. خواشتم که اگر کسی علاقه دارد ایمیل بزند. تعداد زیادی جواب دادند و ابراز علاقه کردند. حالا وقت قدم دوم است.</p>
<p>قدم دوم این است که برای اینکه مسوولین پروژه بتوانند تصمیم بگیرند که با چه کسی کار کنند، می‌خواهند نمونه‌ی کارهای علاقمندان مشارکت در این پرزو‌ه را ببینند.</p>
<p>برای همین از همه‌ی علاقماندان، حتی کسانی که قبلا اعلام آمادگی نکرده بودند، می‌‌خواهم که یک موضوع رایج این روزهای وبلاگستان فارسی را انتخاب کنند و در هفتصد کلمه، به انگلیسی، بنویسند که وبلاگ‌دارهای درباره‌اش چه می‌گویند. لینک به پنج، شش وبلاگ و بازنویسی آنچه آنها از جنبه‌های گوناگون درباره‌ی آن موضوع نوشته‌اند با نقل قول مستقیم از آنها (البته ترجمه شده از فارسی) کافی است. دو سه جمله هم اول کار توضیح دهید که چرا این موضوع مهم است.</p>
<p>متن نمونه را به آدرس ایمیل من hoder@hoder.com و نیز برای افراد زیر تا روز دوشنبه بفرستید:<br />

<title>Dave Winer: Grateful Dead</title>
<link>http://www.scripting.com/blog/categories/gratefulDead.html</link>
<description>A high-fidelity Grateful Dead song every day. This is where we&apos;re experimenting with enclosures on RSS news items that download when you&apos;re not using your computer. If it works (it will) it will be the end of the Click-And-Wait multimedia experience on the Internet. </description>

<description>It&apos;s been a few days since I added a song to the Grateful Dead channel. Now that there are all these new Radio users, many of whom are tuned into this channel (it&apos;s #16 on the hotlist of upstreaming Radio users, there&apos;s no way of knowing how many non-upstreaming users are subscribing, have to do something about this..). Anyway, tonight&apos;s song is a live version of Weather Report Suite from Dick&apos;s Picks Volume 7. It&apos;s wistful music. Of course a beautiful song, oft-quoted here on Scripting News. &lt;i&gt;A little change, the wind and rain.&lt;/i&gt;

<description>Moshe Weitzman says Shakedown Street is what I&apos;m lookin for for tonight. I&apos;m listening right now. It&apos;s one of my favorites. &quot;Don&apos;t tell me this town ain&apos;t got no heart.&quot; Too bright. I like the jazziness of Weather Report Suite. Dreamy and soft. How about The Other One? &quot;Spanish lady come to me..&quot;</description>

<description>Still listening to the US Blues. &lt;i&gt;&quot;Wave that flag, wave it wide and high..&quot;&lt;/i&gt; Mistake made in the 60s. We gave our country to the assholes. Ah ah. Let&apos;s take it back. Hey I&apos;m still a hippie. &lt;i&gt;&quot;You could call this song The United States Blues.&quot;&lt;/i&gt;</description>

<description>Ed Cone: &quot;Had a nice Deadhead experience with my wife, who never was one but gets the vibe and knows and likes a lot of the music. Somehow she made it to the age of 40 without ever hearing Wharf Rat. We drove to Jersey and back over Christmas with the live album commonly known as Skull and Roses in the CD player much of the way, and it was cool to see her discover one the band&apos;s finest moments. That song is unique and underappreciated. Fun to hear that disc again after a few years off -- you get Jerry as blues-guitar hero on Big Railroad Blues and a nice version of Bertha.&quot;</description>

<content:encoded><![CDATA[<p>If you&#8217;ve been having trouble compiling your own PHP installations on Mac OS X 10.6, here&#8217;s the secret to making it not suck! After running the configure script, edit the generated Makefile and make these fixes:</p>
<ul>
<li>Find the <strong>EXTRA_LIBS</strong> definition and add <strong>-lresolv</strong> to the end</li>
<li>Find the <strong>EXE_EXT</strong> definition and remove <strong>.dSYM</strong></li>
</ul>
<p>Standard make and make install should work from here&#8230;</p>
<p>For reference, here&#8217;s the whole configure line I currently use; MySQL is installed from the downloadable installer; other deps from MacPorts:</p>
<p>&#8216;./configure&#8217; &#8216;&#8211;prefix=/opt/php52&#8242; &#8216;&#8211;with-mysql=/usr/local/mysql&#8217; &#8216;&#8211;with-zlib&#8217; &#8216;&#8211;with-bz2&#8242; &#8216;&#8211;enable-mbstring&#8217; &#8216;&#8211;enable-exif&#8217; &#8216;&#8211;enable-fastcgi&#8217; &#8216;&#8211;with-xmlrpc&#8217; &#8216;&#8211;with-xsl&#8217; &#8216;&#8211;with-readline=/opt/local&#8217; &#8211;without-iconv &#8211;with-gd &#8211;with-png-dir=/opt/local &#8211;with-jpeg-dir=/opt/local &#8211;with-curl &#8211;with-gettext=/opt/local &#8211;with-mysqli=/usr/local/mysql/bin/mysql_config &#8211;with-tidy=/opt/local &#8211;enable-pcntl &#8211;with-openssl</p>
