# Automatic Variables:
# $@ The filename representing the target.
# $% The filename element of an archive member specification.
# $< The filename of the first prerequisite.
# $? The names of all prerequisites that are newer than the target, separated by spaces.
# $^ The filenames of all the prerequisites, separated by spaces. This list has dupli-
# cate filenames removed since for most uses, such as compiling, copying, etc.,
# duplicates are not wanted.
#
# $+ Similar to $^, this is the names of all the prerequisites separated by spaces,
# except that $+ includes duplicates. This variable was created for specific situa-
# tions such as arguments to linkers where duplicate values have meaning.
#
# $* The stem of the target filename. A stem is typically a filename without its suffix.
# (We’ll discuss how stems are computed later in the section “Pattern Rules.”) Its
# use outside of pattern rules is discouraged.
