+<a name="Introduction"><H3>Introduction</H3></a>
+Specification of PDF 1.2 enables storing streams in external files.
+The streams, are used to embed Images, Page Descriptions,
+Fonts, etc. into PDF files.
+When creating document collection,
+storing an information shared by several PDF files
+into external files is resonable approach.
+In practice, only fonts are a crutial material used by many PDF files
+in the same PDF collection.
+<P>
+BaKoMa TeX 2.21 supports generating PDF files with embeding fonts
+via external streams stored into common directory.
+
+<a name="Efficiency"><H3>Efficiency of the method</H3></a>
+This feature ables to create documents that share fonts.
+Such approach can drastically reduce size of document
+colections that include large number of PDF files.
+For example, typical conference procedengs (25 articles each is less
+then 10 pages in Computer Modern Fonts) processed with this approach
+requires 3 times less disk space then processed with partial font
+embedding into every article.
+<P>
+It is important that size of font-less PDF files are comparable with
+size of DVI files.
+This hint is useful to estimate size of a document collections.
+
+<a name="Compatibility"><H3>Compatibility with another software</H3></a>
+PDF files refered on external streams can be handled by following
+browsers:
+<UL>
+<LI>Acrobat Reader 3.0 and later handle this feature.
+<LI>GhostScript - beginning from version 5.25 it has code that must
+ handle external streams. However, version&nbsp;5.50 has some error in
+ implementation of this feature.
+ I hope, it will be fixed in version&nbsp;6.0,
+<LI>PDFtoPS (XPDF) don't understand this feature.
+</UL>
+
+It is important, that this method is usefull for distribution
+of documents via CD-ROMs.
+However, this method is unusefull for uploading documents
+on WWW servers. The reason is that some PDF browsers can't handle
+font downloading via network.
+
+<a name="Using"><H3>Generating such PDF's by using BaKoMa TeX</H3></a>
+Beginning from version 2.21 you can generate collection of
+PDF files that share fonts between each other.
+Sharing fonts is implemented by embedding fonts via external streams
+that are placed into separate directory.
+<P>
+To enable this feature choose `<B>Embed to directory</B>' option
+in PDF generation dialog.
+This option is available when <B>PDFFonts</B> subdirectory exists
+anywhere in: <I>current directory</I>, <I>parent directory</I>,
+<I>grand parent directory</I>, etc.
+<P>
+When font sharing is performed by BaKoMa TeX,
+fonts are placed into found <B>PDFFonts</B> directory,
+and <B><I>relative references</I></B> on the fonts are placed into PDF files.
+In this reason, PDF files can be freely moved together with <B>PDFFonts</B>
+directory and with preserving subdirectory structure.
