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')
33#

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

64# Next line is a target dependency line
65# This target entry uses Suffix Replacement within a macro:
66# $(macroname:string1=string2)
67# In the words in the macro named 'macroname' replace 'string1' with 'string2'
68# Below we are replacing the suffix .java of all words in the macro CLASSES
69# with the .class suffix
70#

72classes: $(CLASSES:.java=.class)

75# Next two lines contain a target for running the program
76# Remember the tab in the second line.
77# $(JMV) y $(MAIN) are replaced by their values

82# this line is to remove all unneeded files from
