// Tool for generating RuleBasedBreakIterator data files (.brk files).
|
|
// .brk files contain the precompiled rules for standard types
|
|
// of iterators - word, line, sentence, etc.
|
|
//
|
|
// Usage: genbrk [options] -r rule-file.txt -o output-file.brk
|
|
//
|
|
// options: -v verbose
|
|
// -? or -h help
|
|
//
|
|
// The input rule file is a plain text file containing break rules
|
|
// in the input format accepted by RuleBasedBreakIterators. The
|
|
// file can be encoded as utf-8, or utf-16 (either endian), or
|
|
// in the default code page (platform dependent.). utf encoded
|
|
// files must include a BOM.
