32: * Count parent-child element relations in a corpus of DocBook documents.

36: * For each parent-child relation, print the total number of occurrences,
37: * the parent name, and the child name, separated by tab characters
38: * and followed by a newline character.

40: * Typical usage:
41: * statistics < filenames.txt | sort -n
42: * statistics < filenames.txt | grep '\<listitem\>' | sort -n
1.4 schwarze 43: *
44: * Relations already fully implemented are excluded by default.
45: * The option -a shows all relations.

47: * If two arguments (parent and child) are given, a histogram
48: * of the number of children of the kind in each parent is given
49: * in addition to the normal output.

51: * Example usage:
52: * statistics tgroup colspec < filenames.txt | grep colspec
