+     "This package provides a Java application to query OS information
+designed for use in TeX's shell escape mechanism.  The application can query
+the following:
+
+@itemize
+@item locale and codeset,
+@item current working directory,
+@item user home directory
+@item temporary directory,
+@item OS name, arch and version,
+@item current date and time in PDF format (for TeX formats that don't provide
+@code{\\pdfcreationdate}),
+@item date-time stamp of a file in PDF format (for TeX formats that don't
+provide @code{\\pdffilemoddate}),
+@item size of a file in bytes (for TeX formats that don't provide
+@code{\\pdffilesize}),
+@item contents of a directory (captured as a list),
+@item directory contents filtered by regular expression (captured as a list),
+@item URI or canonical path of a file.  All paths use a forward slash as
+directory divider so results can be used, for example, in commands like
+@code{\\includegraphics}.
+@end itemize
+
+There are files provided for easy access in TeX documents.
+@file{texosquery.tex} provides generic TeX code, whereas @file{texosquery.sty}
+is a LaTeX package, which provides commands to run @command{texosquery} using
+TeX's shell escape mechanism and capture the result in a control sequence.")
