# IRIX inst backend
#
# executables are either going to be mips3 or mips4 and N32 or elf64.
# so the package format is going to be mips3n32
# inst(1M) is the tool for installing packages
# gendist(1M) is the tool for making packages.
#   It takes a tree of files, a spec file and an idb file
#   The spec file is a text description like this:
#     include file
#     define variable value
#     product xx
#        attribute ...
#        image yy
#          attribute ...
#          subsystem zzz
#            attribute ...
#          endsubsys
#        endimage
#     endproduct
#
#   Attributes include
#      id "<title-string>"
#      version <number>
#      mach "<machtag>"
#
#   The idb file contains one line for each file or directory with
#   optional extra attributes
#      config([update|suggest|noupdate])
#      symval(<symlink-target>)
#      postop(cmd)
