+# "patch" script for WebKit Open Source Project, used to apply patches.
+
+# Differences from invoking "patch -p0":
+#
+# Handles added files (does a svn add).
+# Handles removed files (does a svn rm).
+# Has mode where it will roll back to svn version numbers in the patch file so svn can do a 3-way merge.
+#
+# Missing features:
+#
+# Handle binary files.
+# When doing a removal, doesn't check that old file matches what's being removed.
+# Notice a patch that's being applied at the "wrong level" and make it work anyway.
