  3# General notes:
  4#
  5# A number of Make variables are used to generate the crunchgen config file.
  6#
  7#  CRUNCH_SRCDIRS: lists directories to search for included programs
  8#  CRUNCH_PROGS:  lists programs to be included
  9#  CRUNCH_LIBS:  libraries to statically link with
 10#  CRUNCH_SHLIBS:  libraries to dynamically link with
 11#  CRUNCH_BUILDOPTS: generic build options to be added to every program
 12#  CRUNCH_BUILDTOOLS: lists programs that need build tools built in the
 13#       local architecture.
 14#
 15# Special options can be specified for individual programs
 16#  CRUNCH_SRCDIR_$(P): base source directory for program $(P)
 17#  CRUNCH_BUILDOPTS_$(P): additional build options for $(P)
 18#  CRUNCH_ALIAS_$(P): additional names to be used for $(P)
 19#
 20# By default, any name appearing in CRUNCH_PROGS or CRUNCH_ALIAS_${P}
 21# will be used to generate a hard link to the resulting binary.
 22# Specific links can be suppressed by setting
 23# CRUNCH_SUPPRESS_LINK_$(NAME) to 1.
 24#
 25# If CRUNCH_GENERATE_LINKS is set to no, no links will be generated.
