[%CFEngine_function_prototype(filename, comment, split, maxentries, maxbytes)%]

Description: Returns a data container (map) with up to maxentries-1 fields from the first maxbytes bytes of file filename. The first field becomes the key in the map.

One dimension is separated by the regex split, the other by the lines in the file. The array key (the first field) must be unique; if you need to allow duplicate lines use data_readstringarrayidx().

The comment field will strip out unwanted patterns from the file being read, leaving unstripped characters to be split into fields. Using the empty string ("") indicates no comments.
