+# Brief review of the jam language:
+#
+# Statements:
+#   rule RULE - statements to process a rule
+#   actions RULE - system commands to carry out target update
+#
+# Modifiers on actions:
+#   together - multiple instances of same rule on target get executed
+#          once with their sources ($(>)) concatenated
+#   updated - refers to updated sources ($(>)) only
+#   ignore - ignore return status of command
+#   quietly - don't trace its execution unless verbose
+#   piecemeal - iterate command each time with a small subset of $(>)
+#   existing - refers to currently existing sources ($(>)) only
+#   bind vars - subject to binding before expanding in actions
+#
+# Special rules:
+#   ALWAYS - always build a target
+#   DEPENDS - builds the dependency graph
+#   ECHO - blurt out targets on stdout
+#   EXIT - blurt out targets and exit
+#   INCLUDES - marks sources as headers for target (a codependency)
+#   NOCARE - don't panic if the target can't be built
+#   NOUPDATE - create the target if needed but never update it
+#   NOTFILE - ignore the timestamp of the target (it's not a file)
+#   TEMPORARY - target need not be present if sources haven't changed
+#
+# Special variables set by jam:
+#   $(<) - targets of a rule (to the left of the :)
+#   $(>) - sources of a rule (to the right of the :)
+#   $(xxx) - true on xxx (UNIX, VMS, NT, OS2, MAC)
+#   $(OS) - name of OS - varies wildly
+#   $(JAMVERSION) - version number (2.3)
+#
+# Special variables used by jam:
+#   SEARCH - where to find something (used during binding and actions)
+#   LOCATE - where to plop something not found with SEARCH
+#   HDRRULE - rule to call to handle include files
+#   HDRSCAN - egrep regex to extract include files
+#
+# Special targets:
+#   all - default if none given on command line
+#
+
+# Initialize variables
