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