# Provides mechanism for installing whole packages into a specific directory
# structure. This is opposed to the 'install' rule, that installs a number of
# targets to a single directory, and does not care about directory structure at
# all.
# Example usage:
#
# package.install boost : <properties>
# : <binaries>
# : <libraries>
# : <headers>
# ;
#
# This will install binaries, libraries and headers to the 'proper' location,
# given by command line options --prefix, --exec-prefix, --bindir, --libdir and
# --includedir.
#
# The rule is just a convenient wrapper, avoiding the need to define several
# 'install' targets.
#
# The only install-related feature is <install-source-root>. It will apply to
# headers only and if present, paths of headers relatively to source root will
# be retained after installing. If it is not specified, then "." is assumed, so
# relative paths in headers are always preserved.
