+===== open-ils.cstore interface ====
+All methods are prefixed with //open-ils.cstore//.  Parameters are in **bold**.  Examples for srfsh are in ''code'' blocks.
+=== transaction.begin ===
+  * returns new transaction ID on success, execption on failure
+<code>request open-ils.cstore open-ils.cstore.transaction.begin</code>
+=== transaction.{commit|rollback} ===
+  * completes a transaction block
+  * returns transaction ID on success, execption on failure
+<code>request open-ils.cstore open-ils.cstore.transaction.commit "trans-id-foo-1"</code>
+<code>request open-ils.cstore open-ils.cstore.transaction.rollback "trans-id-foo-1"</code>
+=== savepoint.set ===
+  * **new savepoint name** -- existing savepoints are moved forward
+  * returns new savepoint name on success, exception on failure
+<code>request open-ils.cstore open-ils.cstore.savepoint.set "sp-id-foo-1"</code>
+=== savepoint.{release|rollback} ===
+  * **savepoint name**
+  * returns savepoint name on success, exception on failure
+<code>request open-ils.cstore open-ils.cstore.savepoint.release "sp-id-foo-1"</code>
+<code>request open-ils.cstore open-ils.cstore.savepoint.rollback "sp-id-foo-1"</code>
+=== direct.{object}.retrieve ===
+  * **pkey value**
+  * **select/flesh blob**
+    * "flesh" : depth -- link depth to follow when filling in fkeys
+    * "flesh_fields" : { "table id" : [field list], ... } -- limit fkeys to those matching one of [ field list ]
+    * "select" : { "table id" : [ real field list ] -- fields to retrieve (pkey is usually required for fleshing fkeys)
+<code>request open-ils.cstore open-ils.cstore.direct.biblio.record_entry.retrieve 1, {"flesh" : 2, "flesh_fields" : {"bre":["call_numbers"],"acn":["copies"]}}</code>
+=== direct.{object}.search[.atomic] ===
+  * **abstract search style blob** -- { "col" : "val", "col2" : [x,y,z], "col3" : { ">=" : "bar" } }
+  * **select/flesh/order blob** -- Same options as //.retrieve//, with the addition of:
+    * "order_by" : "sorting clause" --  simple ORDER BY clause for core object type
+    * "limit" : maximum number of objects to retrieve, for paging
+    * "offset" : skip this many objects, for paging
+<code>request open-ils.cstore open-ils.cstore.direct.biblio.record_entry.search {"creator" : 1, "create_date" : { "between" : ["2006-06-01","2006-07-01"] } }, {"flesh" : 2, "flesh_fields" : {"bre":["call_numbers"],"acn":["copies"]}}</code>
+//Stream all values in the table, sorted by description field//
+<code>request open-ils.cstore open-ils.cstore.direct.config.i18n_locale.search  {"code": {"!=":null}}, {"order_by": {"i18n_l" : "description"}}</code>
+=== direct.{object}.id_list[.atomic] ===
+  * same as .search, but returns a stream (or an array, for **.atomic**) of object pkey values
+=== direct.{object}.create ===
+  * **new object**
+  * returns new object as represented in DB
+<code>request open-ils.cstore open-ils.cstore.direct.actor.workstation.create { "__c" : "aws", "__p" : [1,null,null,null,"Mike's workstation",18] }</code>
+=== direct.{object}.update ===
+  * **modified object**
+  * returns object ID on success, NULL on failure
+<code>request open-ils.cstore open-ils.cstore.direct.actor.workstation.create { "__c" : "aws", "__p" : [null,1,null,47,"Bill's workstation",18] }</code>
+=== direct.{object}.delete ===
+  * **object or pkey value for deletion**
+  * returns old object ID on success, NULL on failure
+<code>request open-ils.cstore open-ils.cstore.direct.actor.workstation.delete 47</code>
