The str library provides high-level string processing functions, some based on regular expressions. It is intended to support the kind of file processing that is usually performed with scripting languages such as awk, perl or sed.
Programs that use the str library must be linked as follows:
ocamlc other options -I +str str.cma other files ocamlopt other options -I +str str.cmxa other files
For interactive use of the str library, do:
ocamlmktop -o mytop str.cma ./mytop
or (if dynamic linking of C libraries is supported on your platform), start ocaml and type
