+/* dispatch table for VOLUME SET
+ * -----------------------------
+ *
+ * Format of entries:
+ *
+ * First field is the <key>, for the purpose of looking it up
+ * in volume dictionary. Each <key> is of the format "<domain>.<specifier>".
+ *
+ * Second field is <voltype>.
+ *
+ * Third field is <option>, if its unset, it's assumed to be
+ * the same as <specifier>.
+ *
+ * Fourth field is <value>. In this context they are used to specify
+ * a default. That is, even the volume dict doesn't have a value,
+ * we procced as if the default value were set for it.
+ *
+ * Fifth field is <doctype>, which decides if the option is public and available
+ * in "set help" or not. "NODOC" entries are not part of the public interface
+ * and are subject to change at any time. This also decides if an option is
+ * global (apllies to all volumes) or normal (applies to only specified volume).
+ *
+ * Sixth field is <flags>.
+ *
+ * Seventh field is <op-version>.
+ *
+ * There are two type of entries: basic and special.
+ *
+ * - Basic entries are the ones where the <option> does _not_ start with
+ *   the bang! character ('!').
+ *
+ *   In their case, <option> is understood as an option for an xlator of
+ *   type <voltype>. Their effect is to copy over the volinfo->dict[<key>]
+ *   value to all graph nodes of type <voltype> (if such a value is set).
+ *
+ *   You are free to add entries of this type, they will become functional
+ *   just by being present in the table.
+ *
+ * - Special entries where the <option> starts with the bang!.
+ *
+ *   They are not applied to all graphs during generation, and you cannot
+ *   extend them in a trivial way which could be just picked up. Better
+ *   not touch them unless you know what you do.
+ *
+ *
+ * Another kind of grouping for options, according to visibility:
+ *
+ * - Exported: one which is used in the code. These are characterized by
+ *   being used a macro as <key> (of the format VKEY_..., defined in
+ *   glusterd-volgen.h
+ *
+ * - Non-exported: the rest; these have string literal <keys>.
+ *
+ * Adhering to this policy, option name changes shall be one-liners.
