# Generic configuration for Hurd compilation
# Directory makefiles should set the variable makemode to either
# `server' if they compile and install a single program for /hurd
# `utility' if they compile and install a single program for /bin
# `servers' if they compile and install multiple programs for /hurd
# `utilities' if they compile and install multiple programs for /bin
# `library' if they compile and install a library
# `misc' if they do none of those
# Every makefile should define
# SRCS (all actual source code)
# LCLHDRS (all source headers in this directory [NOT MiG created])
# REMHDRS (all Hurd headers in other directories [NOT .defs files])
# Types `server', `utility', and `library' should define
# OBJS (all .o files used to produce the target).
# Types `server', `utility', `servers', and `utilities' should define
# HURDLIBS (all Hurd libraries used, omitting the dirname and the .a.)
# Types `server' and `utility' should define
# OTHERLIBS (all other libraries used)
# target (the name of the program built)
# Types `servers' and `utilities' should define
# targets (the names of all the programs built)
# Type `library' should define
# libname (the name of the library, without .a.)
