About xstr
----------------------------------------------------------------------
This package implements frequent string operations: searching, replacing,
splitting, matching. It is independent from the Str library, and can
replace Str in many cases. Unlike Str, xstr is thread-safe. xstr does
not implement regular expressions in general, but an important subset.
Some operations of xstr are performed as quickly as by Str; if the string
to be processed is small, xstr is often faster than Str; if the string is
big, xstr is upto half as fast than Str.

BUILD:
----------------------------------------------------------------------
make all:
Compiles the bytecode archive.
make opt:
Compiles the native archive.
----------------------------------------------------------------------
INSTALL:
----------------------------------------------------------------------
The module can be installed using the installation method supported by the
"findlib" module. If you have installed "findlib", a "make install" copies
the compiled files to their standard places. The package name is then
"xstr". ("make uninstall" removes the package again.)
If you do not have "findlib", just copy the files manually where you like
them (cp *.cmi *.cma *.cmxa *.a <destination>).
After installation, a "make clean" removes the intermediate files.
----------------------------------------------------------------------
SPEED:
----------------------------------------------------------------------
In the "speed" directory some problems are solved using xstr and Str.
The results on a 486/133Mhz system:
