     21   The BNF grammar is thus:
     22      <depex>   ::= before GUID
     23                  | after GUID
     24                  | SOR <bool>
     25                  | <bool>
     26      <bool>    ::= <bool> and <term>
     27                  | <bool> or <term>
     28                  | <term>
     29      <term>    ::= not <factor>
     30                  | <factor>
     31      <factor>  ::= <bool>
     32                  | <boolval>
     33                  | <depinst>
     34                  | <termval>
     35      <boolval> ::= true
     36                  | false
     37      <depinst> ::= push GUID
     38      <termval> ::= end
