+
+ShopDL is a command-line tool for manipulating TopDL files.
+
+It can be invoked by running the following command on users:
+{{{
+$ /share/benito/util/shopdl.py <topo.xml>
+}}}
+
+Once it begins you will be in an interactive shell. At any time you may run the {{{help}}} command to see the online documentation. You can also ask for help for specific commands.
+{{{
+shopdl> help
+Commands: annotate attributes list save strip
+
+shopdl> help annotate
+Annotates topdl.Computer elements
+Usage: annotate <name=value> <regex-for-node-name>
+}}}
+
+Throughout this documentation I'll be running through some examples with a sample TopDL file. Download the attached {{{two_nodes.xml}}} in order to follow along.
+
+== Regular Expressions ==
+
+Commands which take an argument for a node name always accept regular expressions. This is important to remember when nodes have similar names. For instance the following regular expression will match both {{{bot-10}}} '''and''' {{{bot-100}}}:
+
+{{{
+bot-10
+}}}
+
+If you wish to limit your results to only matching bot-10, you should use a regular expression such as the following:
+
+{{{
+bot-10$
+}}}
+
+== Commands ==
+
+=== Listing Information ===
+
+The two commands used to list information are {{{list}}} and {{{attributes}}}, which list nodes and their attributes respectively.
+
+{{{
+shopdl> list
+node-1
+node-2
+
+shopdl> attributes .*
+node-1:
+    type: pc2133
+    failureaction: fatal
+node-2:
+    type: pc2133
+    failureaction: fatal
+}}}
+
+The attributes listed above are not meaningful to Benito. They are present because this TopDL file was automatically converted from NS.
+
+=== Adding, Modifying, and Deleting ===
+
+The modification commands are {{{annotate}}} and {{{strip}}}, which add/modify attributes and remove them respectively. {{{strip}}} will also remove attributes from substrates, heyoo.
+
+Note that a node or substrate can only have one attribute for a given name. Assigning a new value to an existing attribute will overwrite the previous value.
+
+{{{
+shopdl> annotate benito:node_type=qemu node-1$
+Annotated 1 node
+shopdl> annotate benito:node_type=embedded_pnode node-2$
+Annotated 1 node
+
+shopdl> attributes node-.*
+node-1:
+    type: pc2133
+    failureaction: fatal
+    benito:node_type: qemu
+node-2:
+    type: pc2133
+    failureaction: fatal
+    benito:node_type: embedded_pnode
+}}}
+
+Note also that you can quote the attribute name and value according to shell quoting rules. This allows you to embed spaces.
+
+{{{
+shopdl> strip benito:node_type node-.*
+Removed 2 attributes (searched 2 nodes)
+Removed 0 attributes (searched 1 substrate)
+}}}
+
+Again remember that {{{strip}}} will remove attributes from substrates as well as nodes.
+
+=== Save and/or Quit ===
+
+Save your results using {{{save}}}, quit using {{{quit}}}. {{{save}}} takes an optional parameter to specify output file.
