# Kerberos V5 build tool. Builds Kerberos V5 using a specified
# configuration file to control which support programs are used to
# compile it, which options are given to configure, etc.
#
# usage: kbuild { [ frag ] [ var=value ] [ config-lib-path ] }
# where frag is something like base, or gcc, or cns, where it finds
# base.conf in the config lib path
# var=value sets var to value in the script processing (useful to override
# SRCDIR or KRB4)
# config-lib-path adds itself to the search path for frags.
#
#
# frags themselves are files named frag.conf which have variable settings
# and filenames. # is a comment marker. If the line is an assignment, it's
# read; if it begins with /, it's an explicit member of the path; if it
# doesn't, it's searched for in the path set in the last fragment.
#
# for example, at mit, one might say
#
# /mit/krb5/sandbox/util/kbuild base suncc athena
#
# or at cygnus, one might say
#
# /6h/eichin/mit-v5/build/base/util/kbuild base gcc cns
#
# You get the idea.
