#
# 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
# PKG_CONFIG: pkg-config tool

# All the above variables have a counterpart variable for the build tool,

# defining DPKG_EXPORT_BUILDTOOLS.
