Support for PDF/A

For MacOSX:

For Ubuntu / Debian:

 apt-get install poppler ghostscript

A PDF/A document is just a PDF document that uses a specific subset of PDF that is designed to ensure it is 'self-contained'. It's not permitted to be reliant on information from external sources (e.g. font programs and hyperlinks).

From wikipedia:

Other key elements to PDF/A compatibility include:

• Audio and video content are forbidden.
• JavaScript and executable file launches are forbidden.
• All fonts must be embedded and also must be legally embeddable for unlimited, universal rendering. This also applies to the so-called
  PostScript standard fonts such as Times or Helvetica.
• Colorspaces specified in a device-independent manner.
• Encryption is disallowed.
• Use of standards-based metadata is mandated.

Is it any good?

Yes.
