This Lua library allows you to validate ISBN numbers, correct the checksums
on invalid ones, format them using the standard arrangement of hyphens,
compare values for equivalence, and extract individual parts of the value.
Both ISBN-10 and ISBN-13 are supported.

The Lua-ISBN library is written in pure Lua.  No C compilation is required
to install it.

When you unpack the source code everything should already be ready for
installation.  Doing "make install" as root will install the Lua source
files and a man page lua-isbn(3) containing the documentation.

The latest packages and online documentation are available from the module's
website:
