+  Configure ImageMagick policies.
+
+  Domains include system, delegate, coder, filter, path, or resource.
+
+  Rights include none, read, write, and execute.  Use | to combine them,
+  for example: "read | write" to permit read from, or write to, a path.
+
+  Use a glob expression as a pattern.
+
+  Suppose we do not want users to process MPEG video images:
+
+    <policy domain="delegate" rights="none" pattern="mpeg:decode" />
+
+  Here we do not want users reading images from HTTP:
+
+    <policy domain="coder" rights="none" pattern="HTTP" />
+
+  Lets prevent users from executing any image filters:
+
+    <policy domain="filter" rights="none" pattern="*" />
+
+  The /repository file system is restricted to read only.  We use a glob
+  expression to match all paths that start with /repository:
+  
+    <policy domain="path" rights="read" pattern="/repository/*" />
+
+  Let's prevent possible exploits by removing the right to use indirect reads.
+
+    <policy domain="path" rights="none" pattern="@*" />
+
+  Any large image is cached to disk rather than memory:
+
+    <policy domain="resource" name="area" value="1GB"/>
+
+  Define arguments for the memory, map, area, width, height, and disk resources
+  with SI prefixes (.e.g 100MB).  In addition, resource policies are maximums
+  for each instance of ImageMagick (e.g. policy memory limit 1GB, -limit 2GB
+  exceeds policy maximum so memory limit is 1GB).
