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