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.
