# $Id$
#
# Creates an ACE build tree in directory "build/<build name>" below the current
# directory, which must be an ACE "top level" directory (such as
# $ACE_ROOT). The build tree directory structure mirrors that of the ACE
# top level directory structure, except that instead of containing any plain
# files, it contains only symlinks to the files in the ACE top level structure.
#
# This program has a similar purpose to "clone", but in addition to
# only creating symlinks (clone creates hard links, by default), this
# script:
# 1) uses relative rather than absolute symlinks,
# 2) tries not to put junk files into the build tree,
# 3) only creates a new tree in a build/ directory below the current,
# top level ACE directory (it's a feature :-), but it does enforce
# consistency), and
# 4) is ACE-specific, so it can always create the ChangeLog symlink,
# for example.
#
# This program can be re-run on a build tree at any time in order to
# update it. It will only add new symlinks, it won't remove any that
# are no longer valid. If you want to do that, it's easiest just to
# remove the build completely and start from scratch.
#
# If the <build name> starts with "build/", that part will be removed
# from it.
#
# The first three lines above let this script run without specifying the
# full path to perl, as long as it is in the user's PATH.
# Taken from perlrun man page.
