# Script to generate IDL from all of the relevant NCBI ASN.1 specifications.
#
# J. Epstein, NCBI, 8/28/1996
#
# Requirements for building the IDL:
#   a) a compiled copy of 'snacc'.  The source code is available, e.g. at
#      ftp://www.fokus.gmd.de/pub/freeware/snacc/snacc-1.2rj.9.tar.gz
#   b) an unpacked copy of the NCBI toolkit
#   c) the 'asntool' utility built from the NCBI toolkit
#
# Preferably this script should be run in a directory which is either empty
# or only contains the script itself.
#
#
# The following variables should be modified to match the directory structure
# at your site
#
snacchome=$HOME/snacc/snacc-1.2rj.9
snacc=$snacchome/compiler/snacc
ncbihome=$HOME/ncbi
asntool=$ncbihome/build/asntool
useful=asn-useful.asn1
#
rm -f *.asn $useful xx?? *.idl
rm -rf scratch
cp $snacchome/asn1specs/$useful .
#
# Process the $useful file to include the NCBI "StringStore" type
#
patch $useful <<EOF >/dev/null 2>&1
