  11 # Clear any default targets for building .class files from .java files; we
  12 # will provide our own target entry to do this in this makefile.
  13 # make has a set of default targets for different suffixes (like .c.o)
  14 # Currently, clearing the default for .java.class is not necessary since
  15 # make does not have a definition for this target, but later versions of
  16 # make may, so it doesn't hurt to make sure that we clear any default
  17 # definitions for these

  24 # Here is our target entry for creating .class files from .java files
  25 # This is a target entry that uses the suffix rule syntax:
  26 #       DSTS:
  27 #               rule
  28 # DSTS (Dependency Suffix     Target Suffix)
  29 # 'TS' is the suffix of the target file, 'DS' is the suffix of the dependency
  30 #  file, and 'rule'  is the rule for building a target
  31 # '$*' is a built-in macro that gets the basename of the current target
  32 # Remember that there must be a < tab > before the command line ('rule')

  40 # CLASSES is a macro consisting of N words (one for each java source file)
  41 # When a single line is too long, use \<return> to split lines that then will be
  42 # considered as a single line. For example:
  43 # NAME = Camilo \
  44          Juan
  45 # is understood as
  46 # NAME = Camilo        Juan
