3 # Create cdb file from flat alias file. DPC: 15/10/98.
4 # Args: source (may be relative or absolute)
5 # target (may be relative or absolute. Default = source)
6 # Generates: target.cdb
7 # target.tmp
8 #
9 # Little Perl script to convert flat file into CDB file. Two advantages over
10 # cdbmake-12 awk script that is distributed with CDB:
11 # 1) Handles 'dpc22:dpc22@hermes' as well as 'dpc22 dpc22@hermes'
12 # 2) Perl works with arbitary length strings: awk chokes at 1,024 chars
