#! @_PATH_SH@
## $Id: fixscript.in 2805 1999-11-27 07:23:49Z rra $
##
## Fix interpretor paths and INN variable load paths.
##
## Scripts shipped with INN always have the invocation path for the
## interpretor on the first line and the command to load INN variable
## settings into the script on the second line. For example, for a Bourne
## shell script:
##
## #!/bin/sh
## . /var/news/lib/innshellvars
##
## This script takes as input such a script and outputs the same script
## with the first two lines replaced to have the correct path to the
## interpretor and to the INN variable library, as determined by configure.
##
## If the script is invoked with the -i flag, only fix the interpretor
## path and don't modify the second line of the file to include the
## appropriate innshellvars.
