Explicit form
Each record in a catalog file consists of a sequence of lines and is delimited from
its succesor by an empty line.
A (key, value) pair is usually written in the form:
key==value | date==Sat, Jun 29, 1996 |
If the data value includes the new line characters, then the data should be written in the form:
key=+delim value delim | address=+EOV IMFM Jadranska 19 1000 Ljubljana EOV |
For the delimiter delim we can use any string, which does not appear as a substring in string value.
