-<h1>Policy on removing features from OpenOCD</h1>\r
-If a feature in OpenOCD is known to be broken and nobody has\r
-submitted a fix and the feature is causing trouble for\r
-maintainence, it can be removed from OpenOCD trunk. The threshold\r
-for temporarily removing something from OpenOCD trunk is low to\r
-ease maintainence and place the burden of maintainence on\r
-those that care about a feature. \r
-<p>\r
-Note that code is never deleted from OpenOCD svn, it remains\r
-in svn so if somebody sees a feature removed that they would\r
-like kept, they have but to port and fix that feature\r
-back up to main trunk. This document can be helpful in this\r
-regard in that the latest working version and the known broken\r
-version may be listed. \r
-<h1>Policy on adding features from OpenOCD</h1>\r
-To add a feature to OpenOCD, generally it should not break any existing\r
-features and it should be functional and the code reasonably readable\r
-and useful to others in the OpenOCD community. The code does not\r
-have to be completed. Work in progress is fine for OpenOCD trunk.\r
-<p>\r
-Also new tests should be defined. Note that the code does not have\r
-to pass all the tests. In fact it can be helpful to have tests\r
-to describe facets that really should be working, but aren't\r
-done yet.\r

+those that care about a feature.
+<p>
+Note that code is never deleted from OpenOCD svn, it remains
+in svn so if somebody sees a feature removed that they would
+like kept, they have but to port and fix that feature
+back up to main trunk. This document can be helpful in this
+regard in that the latest working version and the known broken
+version may be listed.
+<h1>Policy on adding features from OpenOCD</h1>
+To add a feature to OpenOCD, generally it should not break any existing
+features and it should be functional and the code reasonably readable
+and useful to others in the OpenOCD community. The code does not
+have to be completed. Work in progress is fine for OpenOCD trunk.
+<p>
+Also new tests should be defined. Note that the code does not have
+to pass all the tests. In fact it can be helpful to have tests
+to describe facets that really should be working, but aren't
+done yet.
