+# This Makefile snippet defines the following variables for host tools:
+#
+# AS: assembler
+# CPP: C preprocessor
+# CC: C compiler
+# CXX: C++ compiler
+# OBJC: Objective C compiler
+# OBJCXX: Objective C++ compiler
+# GCJ: GNU Java compiler
+# F77: Fortran 77 compiler
+# FC: Fortran 9x compiler
+# LD: linker
+# STRIP: strip objects
+# OBJCOPY: copy objects
+# OBJDUMP: dump objects
+# NM: names lister
+# AR: archiver
+# RANLIB: archive index generator
+# PKG_CONFIG: pkg-config tool
+#
+# All the above variables have a counterpart variable for the build tool,
+# as in CC → CC_FOR_BUILD.
+#
+# The variables are not exported by default. This can be changed by
+# defining DPKG_EXPORT_BUILDTOOLS.
