Adding a new reactor...

...for supporting Internet Explorer's kludge in not allowing .eml to
be opened (and giving you no clues as to why it's not opening it,
either. :P). Read detectors/filereactor.py for more information.

+        To work around this behavior, rename the .EML file that the URL links to so that it has a .MHT file name extension, and then update the URL to reflect the change to the file name. To do this:
+
+        1. In Windows Explorer, locate and then select the .EML file that the URL links.
+        2. Right-click the .EML file, and then click Rename.
+        3. Change the file name so that the .EML file uses a .MHT file name extension, and then press ENTER.
+        4. Updated the URL that links to the file to reflect the new file name extension."

 =========================
 
+
+0.8.0 Added filereactor detector
+--------------------------------
+
+This reactor is not installed by default, but rather can be found in the source
+directory, under the detectors/ directory.
+
+In it, it contains a workaround for an Internet Explorer limitation, regarding
+.eml and .mht files. It is tested to work with both Internet Explorer 6 and
+Mozilla's Firefox.

+Read the description inside of the reactor itself, for more information.

 0.8.0 Added Dispatcher role
