 The stock circ scripts (and in-db circ matrix) will always target the "default" rule here.  An item circulating under this rule will start with 2 allowed renewals, and either circulate for 7, 14, or 21 days depending on the value of the item's //Loan Duration// field (which can have the values Short, Normal, or Long, corresponding with the **shrt**, **normal**, and **extended** columns in the rule table). The stock circ scripts (and in-db circ matrix) will always target the "default" rule here.  An item circulating under this rule will start with 2 allowed renewals, and either circulate for 7, 14, or 21 days depending on the value of the item's //Loan Duration// field (which can have the values Short, Normal, or Long, corresponding with the **shrt**, **normal**, and **extended** columns in the rule table).
  
-The circ scripts reference these rules by the value in the **name** column.  The circ matrix tables reference these rules by the value in their **id** column.  A common practice is to embed the values for a rule into the rule name itself, as seen above, to make it easier to understand and manage the circ scripts.  It could also make sense to use names like "audiobook" or "bestseller", but those sort of labels are more often used with item //circulation modifiers//, to push configurability more toward end-user staff and away from admins.  It also helps facilitate the configuration of rules that may be different per library in a shared system.  Consider that two libraries may both have an "audiobook" circ modifier, yet based on the circ scripts, a different loan duration rule may be chosen.  If those loan duration rules are named after their values, then they'll never be changed and potentially surprise a library that targets them.+The circ scripts reference these rules by the value in the **name** column.  The circ matrix tables reference these rules by the value in the **id** column.  A common practice is to embed the values for a rule into the rule name itself, as seen above, to make it easier to understand and manage the circ scripts.  It could also make sense to use names like "audiobook" or "bestseller", but those sort of labels are more often used with item //circulation modifiers//, to push configurability more toward end-user staff and away from admins.  It also helps facilitate the configuration of rules that may be different per library in a shared system.  Consider that two libraries may both have an "audiobook" circ modifier, yet based on the circ scripts, a different loan duration rule may be chosen for each of them.  If the loan duration rules are named after their values, then they'll never be changed and potentially surprise a library that targets them.  However, if a shared system is strong on shared policies, it may be easier to manipulate the rule table itself whenever that policy changes.  It's up to you find the right balance for your system.

 +==== Description of Default Files ====
 +These files are found in /openils/var on your Evergreen server.
 +
 +=== circ/circ_lib.js ===
 +  * this file contains a library of often used functions and constants.  these can be called in other scripts and you can add your own utility functions here.
 +  * Some examples:
 +    * findGroupConfig(): returns the config values from circ_groups.js
 +    * isGroupDescendant( parent, child): returns true if the child patron group is a descendent of the parent
 +    * isPrecat: a constant that returns true/false if an item is a pre-cat
 +
 +=== circ/circ_duration.js ===
 +  * this file is called when an item is checked out and results in:
 +    * loan duration rule
 +    * recurring fine rule
 +    * max fine rule
 +
 +=== circ/circ_groups.js ===
 +  * this file determines patron limits
 +  * the function findGroupConfig() retrieves values from this file
 +    * this function is called in circ_permit_hold.js, circ_permit_patron.js and patron_penalty.js
 +
 +=== circ/circ_permit_copy.js ===
 +=== circ/circ_permit_patron.js ===
 +=== penalty/patron_penalty.js ===
 +
 +=== circ/circ_permit_hold.js ===
 +  * called on renewal, can be used to prevent holds
 +=== circ/circ_permit_renew.js ===
