# InstallConf.awk Apache HTTP 2.x script to rewrite the @@ServerRoot@@
# tags in httpd.conf.in to original\httpd.conf - then duplicate the
# conf files to the 'live' configuration if they don't already exist.
#
# Note that we -don't- want the ARGV file list, so no additional {} blocks
# are coded.  Use explicit args (more reliable on Win32) and use the fact
# that ARGV[] params are -not- '\' escaped to process the C:\Foo\Bar Win32
# path format.  Note that awk var=path would not succeed, since it -does-
# escape backslashes in the assignment.  Note also, a trailing space is
# required for paths, or the trailing quote following the backslash is
# escaped, rather than parsed.
