For a long time pdfLaTeX has offered the command \pdfannot for
inserting arbitrary PDF annotations. However, the command is
presented in a form where additional knowledge of the
definition of the PDF format is indispensable. This package is
an answer to the - occasional - questions in newsgroups, about
how one could use the comment function of Adobe Reader. At
least for the writer of LaTeX code, the package offers a
convenient and user-friendly means of using \pdfannot to
provide comments in PDF files. Since version v1.1,
pdfcomment.sty also supports LaTeX - dvips - ps2pdf, LaTeX -
dvipdfmx, and XeLaTeX. Unfortunately, support of PDF
annotations by PDF viewers is sparse to nonexistent. The
reference viewer for the development of this package is Adobe
Reader.
