;;;; Parse ANSI test results from a s-expr database, allowing queries
;;;; to show differences.

To use 

1.  Create a "database" of test results consisting of s-exps.  A
    default database is in 'failures'.
   
    The s-exprs have the form:
   
   (compileit|doit <version> :id <id> [:<key> <value>] 
     (<failing test results>))

where

   compileit|doit   The symbol 'compileit' or 'doit' depending on
                    whether the compiled or interpreted tests were run.

   version          A symbol identifying the version of source of the
                    tests (i.e. r12506 or 0.18.0)

   :id <id>         <id> is a symbol identifying the environment for
                    the tests

   :key <value>     Additional key-value pairs

   <failing test results>
                    The list of symbols failing the tests.

An example on an entry:

  (doit r12506 :id jupiter
      :uname "i386-pc-solaris2.11"  :jvm "jdk-1.6.0_13"
   (REINITIALIZE-INSTANCE.ERROR.1 DEFGENERIC.ERROR.20
    DEFGENERIC.ERROR.21 DEFGENERIC.30 CALL-NEXT-METHOD.ERROR.1
    CALL-NEXT-METHOD.ERROR.2 DEFMETHOD.ERROR.14 DEFMETHOD.ERROR.15
    INVOKE-DEBUGGER.1 MAKE-CONDITION.3 MAKE-CONDITION.4
    DELETE-PACKAGE.5 DELETE-PACKAGE.6 MAP.48 TYPE-OF.1 TYPE-OF.4
    CHAR-UPCASE.2 CHAR-DOWNCASE.2 FRESH-LINE.5 PRINT.RANDOM-STATE.1
    PPRINT-FILL.14 PPRINT-FILL.15 PPRINT-LINEAR.14 PPRINT-TABULAR.13
    PPRINT-LOGICAL-BLOCK.17 PPRINT-POP.7 PPRINT-POP.8
    FORMAT.LOGICAL-BLOCK.CIRCLE.1 FORMAT.LOGICAL-BLOCK.CIRCLE.2
    FORMAT.LOGICAL-BLOCK.CIRCLE.3 FORMAT.JUSTIFY.30 FORMAT.JUSTIFY.32
    WITH-STANDARD-IO-SYNTAX.23))

2.  Run (PARSE [<filename>]) on the file of your database.  Without an
    argument, the default database is read.

3.  Then differences between versions can be queried via REPORT

   CL-USER> (REPORT 'compileit '0.18.0 'r13590)
