;; Custom filters and template code added below...
;; =============================================================================

;; This filter is for converting Integers used to store Boolean values
;; in a SQLite database. The intended place you will use this filter
;; is in the /software section. The most notable parts being the /add
;; and /edit sections. In the SQLite database, I have set:
;; - 0 => false
;; - 1 => true.
;; In this case, if the `VALUE' is not 1, it is always false (I.E. 0).
