Refiddle Makefile

  • Update MANIFEST to just include the file sublists instead of duplicating entries
  • Update file sublists and MANIFEST to reflect added and removed files
  • Fix ##uselib## substitution on 'make install' so that it really substitutes; seems to have been a combination of conflicting quoting and special characters
  • Property svn:executable set to *
  • Property svn:keywords set to Date Rev Author Id

64 The directory containing any given datafile must be writable.
65 -c Convert any A+PTR (=) record to a bare PTR if the forward domain is
66 not present in the database. Note this does NOT look forward through
67 a single file, nor across multiple files handled in the same run.
68 Multiple passes may be necessary if SOA and = records are heavily
69 intermixed and not clustered together.
70 -l (for "legacy") Force import of A+PTR records as-is. Mutually exclusive
71 with -c. -l takes precedence as -c is lossy.
72 -t Trial run mode; spits out records that would be left unimported.
73 Disables -r if set.
74
75 -r and -c may be combined (-rc)
76
77 datafileN is any tinydns record data file.
