-# defined a domain-specific language for specifying MARC tags to be dropped from

-#
-# each line may specify any number of tags to be included, either singly (\d{1,3})
-# or as a range (\d{1,3}\.\.\d{1,3}
-#
-# if a single number is given, it must be between '000' and '999', inclusive.
-#
-# ranges obey the previous rule, and also the first number of the range must be less
-# than the second number
-#
-# finally, any single range in a line may be followed by the keyword 'except'. every
-# number or range after 'except' is excluded from the range specified. all these
-# numbers must actually be within the range.
-#
-# specifying a tag twice is an error, to help prevent typos

-The marc-cleanup trash tags file is a simple plaintext file. It is a
-line oriented format. There are three basic tokens:
-
- * The tag
- * The tag range
- * The "except" clause
-
-Any number of tags and/or tag ranges can appear on a single line. A
-tag cannot appear twice in the file, either alone or as part of a
-range. This is to prevent errors in the trash tag listing. Items do
-not have to be sorted within a line. These following lines are valid:
-
- 850 852 870..879 886 890 896..899
- 214 696..699 012
-
-Ranges must be ordered internally. That is, "870..879" is valid while
-"879..870" is not.
-
-Finally, there can be only one "except" clause on a line. It is
-composed of the word "except" followed by one or more tags or
-ranges. Except clauses must follow a range, and all tags within the
-clause must be within the range which the clause follows.
+See
- 900..997 except 935 950..959 987 994
+http://intra.lan.hq.esilibrary.com/dokuwiki/doku.php?id=migration:tag_files
-is a valid example.
+for tag file syntax information.
