I've been wanting to add National Language Support to Shadow for some
time now but there is no freely redistributable NLS package that I am
aware of.  I found some stuff in an old hacked up ELM directory, but
it didn't look to be complete.  This isn't what I'd call "complete",
but it's better than anything I've found.  And it includes a sample
message catalog for the three commands that are included.

X
XThis documents purpose is to state the conditions under which this
XPackage (See definition below) viz: "NLS-LIB", the National Language
XLibrary which is held in John Frederick Haugh, II, may be copied, such
Xthat the copyright holder maintains some semblance of artistic control
Xover the development of the package, while giving the users of the
Xpackage the right to use and distribute the Package in a more-or-less
Xcustomary fashion, plus the right to make reasonable modifications.
X
XSo there.

X***************************************************************************
X
XDefinitions:
X
X
XA "Package" refers to the collection of files distributed by the
XCopyright Holder, and derivatives of that collection of files created
Xthrough textual modification, or segments thereof.
X
X"Standard Version" refers to such a Package if it has not been modified,
Xor has been modified in accordance with the wishes of the Copyright
XHolder.
X
X"Copyright Holder" is whoever is named in the copyright or copyrights
Xfor the package.
X
X"You" is you, if you're thinking about copying or distributing this
XPackage.
X
X"Reasonable copying fee" is whatever you can justify on the basis of
Xmedia cost, duplication charges, time of people involved, and so on.
X(You will not be required to justify it to the Copyright Holder, but
Xonly to the computing community at large as a market that must bear the
Xfee.)
X
X"Freely Available" means that no fee is charged for the item itself,
Xthough there may be fees involved in handling the item.  It also means
Xthat recipients of the item may redistribute it under the same
Xconditions they received it.
X
X
X1.  You may make and give away verbatim copies of the source form of the
XStandard Version of this Package without restriction, provided that you
Xduplicate all of the original copyright notices and associated
Xdisclaimers.
X
X2.  You may apply bug fixes, portability fixes and other modifications
Xderived from the Public Domain or from the Copyright Holder.  A Package
Xmodified in such a way shall still be considered the Standard Version.
X
X3.  You may otherwise modify your copy of this Package in any way,
Xprovided that you insert a prominent notice in each changed file stating
Xhow and when AND WHY you changed that file, and provided that you do at
Xleast ONE of the following:
X
Xa) place your modifications in the Public Domain or otherwise make them
XFreely Available, such as by posting said modifications to Usenet or an
Xequivalent medium, or placing the modifications on a major archive site
Xsuch as uunet.uu.net, or by allowing the Copyright Holder to include
Xyour modifications in the Standard Version of the Package.
X
Xb) use the modified Package only within your corporation or organization.
X
Xc) rename any non-standard executables so the names do not conflict with
Xstandard executables, which must also be provided, and provide separate
Xdocumentation for each non-standard executable that clearly documents
Xhow it differs from the Standard Version.
X
Xd) make other distribution arrangements with the Copyright Holder.
X
X4.  You may distribute the programs of this Package in object code or
Xexecutable form, provided that you do at least ONE of the following:
X
Xa) distribute a Standard Version of the executables and library files,
Xtogether with instructions (in the manual page or equivalent) on where
Xto get the Standard Version.
X
Xb) accompany the distribution with the machine-readable source of the
XPackage with your modifications.
X
Xc) accompany any non-standard executables with their corresponding
XStandard Version executables, giving the non-standard executables
Xnon-standard names, and clearly documenting the differences in manual
Xpages (or equivalent), together with instructions on where to get the
XStandard Version.
X
Xd) make other distribution arrangements with the Copyright Holder.
X
X5.  You may charge a reasonable copying fee for any distribution of this
XPackage.  You may charge any fee you choose for support of this Package.
XYOU MAY NOT CHARGE A FEE FOR THIS PACKAGE ITSELF.  However, you may
Xdistribute this Package in aggregate with other (possibly commercial)
Xprograms as part of a larger (possibly commercial) software distribution
Xprovided that YOU DO NOT ADVERTISE this package as a product of your
Xown.
X
X6.  The name of the Copyright Holder may not be used to endorse or
Xpromote products derived from this software without specific prior
Xwritten permission.
