   8 # Provides mechanism for installing whole packages into a specific directory
   9 # structure. This is opposed to the 'install' rule, that installs a number of
  10 # targets to a single directory, and does not care about directory structure at
  11 # all.
  12
  13 # Example usage:
  14 #
  15 #   package.install boost : <properties>
  16 #                         : <binaries>
  17 #                         : <libraries>
  18 #                         : <headers>
  19 #                         ;
  20 #
  21 # This will install binaries, libraries and headers to the 'proper' location,
  22 # given by command line options --prefix, --exec-prefix, --bindir, --libdir and
  23 # --includedir.
  24 #
  25 # The rule is just a convenient wrapper, avoiding the need to define several
  26 # 'install' targets.
  27 #
  28 # The only install-related feature is <install-source-root>. It will apply to
  29 # headers only and if present, paths of headers relatively to source root will
  30 # be retained after installing. If it is not specified, then "." is assumed, so
  31 # relative paths in headers are always preserved.
