\textbf{Note: This package is obsolete. For \LaTeX-format \hbox{2020-10-01} and newer:
Instead of }\verb|\addglobalwarning{ something }|\textbf{ use }
\verb|\AddToHook{enddocument/info}{ something }|\textbf{ and do not load the warning package.}}

Sometimes a class or package has to make a global warning such as
``Rerun for this or that reason'' or ``This is draft, change this
before the final run''. If you are generating them with
\verb+\AtEndDocument{\PackageWarningNoLine+\marg{packagename}\marg{warning}\verb+}+
the warning appears very early before the filelist. Then the
warning can easily be overseen. This package provides a command
that surely puts the warning at the end near to the global
warnings generated by \LaTeX\ itself.
You can add a warning to a list of user defined warnings using the
command \cmd{\addglobalwarning} as it can be seen in the example below.

This package could be useful for the warnings generated e.\,g.\ by
the packages \pkg{changebar.sty} or \pkg{longtable.sty}.
