- * plstr.h
- *
- * This header file exports the API to the NSPR portable library or string-
- * handling functions.  
- * 
- * This API was not designed as an "optimal" or "ideal" string library; it 
- * was based on the good ol' unix string.3 functions, and was written to
- *
- *  1) replace the libc functions, for cross-platform consistency, 
- *  2) complete the API on platforms lacking common functions (e.g., 
- *     strcase*), and
- *  3) to implement some obvious "closure" functions that I've seen
- *     people hacking around in our code.
- *
- * Point number three largely means that most functions have an "strn"
- * limited-length version, and all comparison routines have a non-case-
- * sensitive version available.
