+# Case conversion macros. Taken from
+# http://git.buildroot.net/buildroot/tree/package/pkg-utils.mk. This
+# is inspired by the 'up' macro from gmsl (http://gmsl.sf.net). It is
+# optimised very heavily because these macros are used a lot. It is
+# about 5 times faster than forking a shell and tr.
+#
+# The caseconvert-helper creates a definition of the case conversion macro.
+# After expansion by the outer $(eval ), the UPPERCASE macro is defined as:
+# $(strip $(eval __tmp := $(1)) $(eval __tmp := $(subst a,A,$(__tmp))) ... )
+# In other words, every letter is substituted one by one.
+#
+# The caseconvert-helper allows us to create this definition out of the
+# [FROM] and [TO] lists, so we don't need to write down every substition
+# manually. The uses of $ and $$ quoting are chosen in order to do as
+# much expansion as possible up-front.
+#
+# Note that it would be possible to conceive a slightly more optimal
+# implementation that avoids the use of __tmp, but that would be even
+# more unreadable and is not worth the effort.
