        This is the README file for the LaTeX2e package
        `libgreek', version 1.1 of 2022/11/11.

        This Work includes libgreek.sty, libgreek-legacy.sty, as
        well as the documentation libgreek.pdf, this README and
        the source file libgreek.dtx.

With \usepackage{libgreek} the Greek letters in math mode
will be extracted from font support files included with the
`libertinus-type1' package maintained by Bob Tennent.

The shape of the Greek letters are configured via package
options, and they also come in \...up and \...it variants.

On old systems having kept the now obsolete `libertine-legacy'
(also maintained by Bob Tennent), `libgreek' will hand over
automatically to a secondary package `libgreek-legacy' which
for backwards compatibility is almost identical to the initial
1.0 release of 2011/03/14 of `libgreek'.  This legacy mode
does not provide the \...up and \...it control sequences.

Manual installation:
-------------------

Execute                  This creates	       
			 		       
    etex libgreek.dtx	     libgreek.sty       
			     libgreek-legacy.sty
			     libgreek.tex

The first two are the package files. The last one is for
building the PDF documentation.

To build the PDF:

    latexmk  libgreek.tex
    dvipdfmx libgreek.dvi

********** This is possible only on a system with the
********** libertine-legacy package available to LaTeX.

The PDF documentation then includes the commented source code.

It is possible to run latex + dvipdfmx, pdflatex, lualatex, or
xelatex directly on libgreek.dtx rather than on libgreek.tex.
The PDF will then not included the commented source code.

Whether with or without source code, PDF produced via latex +
dvipdfmx or xelatex has smaller size than the one from
pdflatex or lualatex due to font compression differences.
