translators: projects/entities merged

[René Ladan]

Dear translators,

now that the projects/entities is merged back into head/ as of r42226,
you will have to update the author entity references in your books and
articles to avoid loosing email addresses in the rendered output:

Before:
* share/xml/authors.ent :
  <!ENTITY a.et "ExtraTerrestial <email>et at FreeBSD.org</email>">

* articles/martian/article.xml:

  <para>The first green man to join &os; was &a.et;.</para>

which would render as

<para>The First green man to join FreeBSD was ExtraTerrestial <a href
....>et at FreeBSD.org</a>.</para>

After:
* share/xml/authors.ent :
  <!ENTITY a.et "ExtraTerrestial">
  <!ENTITY a.et.email "&a.et; <email xmlns=''>et at FreeBSD.org</email>">

(the empty namespace is required for the webpages to build)

This means the same sentence would now render without the email address,
unless you change it to:

<para>The first green man to join &os; was &a.et.email;.</para>

Regards,
René
