# Say that you have a Pisa.java source file.  Here we install both
# Pisa.class (the main class) and also, if they exist, all class files
# with names beginning wih Pisa$ (such as Pisa$1$Nicola.class); these
# files are generated for nested/inner classes, and must be installed
# as well.  The fact we need to install these files is the reason why
# the following is more complicated than you would think at first
# glance.

# Build efficiently the list of possible inner/nested classes 

# We first build a list like in `Pisa[$]*.class Roma[$]*.class' by
# taking the JAVA_OBJ_FILES and replacing .class with [$]*.class, then
# we use wildcard to get the list of all files matching the pattern
UNESCAPED_ADD_JAVA_OBJ_FILES = $(wildcard $(JAVA_OBJ_FILES:.class=[$$]*.class))

# Finally we need to escape the $s before passing the filenames to the
# shell
