137 # Brief review of the jam language:
138 #
139 # Statements:
140 # rule RULE - statements to process a rule
141 # actions RULE - system commands to carry out target update
142 #
143 # Modifiers on actions:
144 # together - multiple instances of same rule on target get executed
145 # once with their sources ($(>)) concatenated
146 # updated - refers to updated sources ($(>)) only
147 # ignore - ignore return status of command
148 # quietly - don't trace its execution unless verbose
149 # piecemeal - iterate command each time with a small subset of $(>)
150 # existing - refers to currently existing sources ($(>)) only
151 # bind vars - subject to binding before expanding in actions
152 #
153 # Special rules:
154 # Always - always build a target
155 # Depends - builds the dependency graph
156 # Echo - blurt out targets on stdout
157 # Exit - blurt out targets and exit
158 # Includes - marks sources as headers for target (a codependency)
159 # NoCare - don't panic if the target can't be built
160 # NoUpdate - create the target if needed but never update it
161 # NotFile - ignore the timestamp of the target (it's not a file)
162 # Temporary - target need not be present if sources haven't changed
163 #
164 # Special variables set by jam:
165 # $(<) - targets of a rule (to the left of the :)
166 # $(>) - sources of a rule (to the right of the :)
167 # $(xxx) - true on xxx (UNIX, VMS, NT, OS2, MAC)
168 # $(OS) - name of OS - varies wildly
169 # $(JAMVERSION) - version number (2.5)
170 #
171 # Special variables used by jam:
172 # SEARCH - where to find something (used during binding and actions)
173 # LOCATE - where to plop something not found with SEARCH
174 # HDRRULE - rule to call to handle include files
175 # HDRSCAN - egrep regex to extract include files
176 #
177 # Special targets:
178 # all - default if none given on command line
