+Emacs packages should preferably use the Emacs build system
+(@pxref{emacs-build-system}), for uniformity and the benefits provided
+by its build phases, such as the auto-generation of the autoloads file
+and the byte compilation of the sources.  Because there is no
+standardized way to run a test suite for Emacs packages, tests are
+disabled by default.  When a test suite is available, it should be
+enabled by setting the @code{#:tests?} argument to @code{#true}.  By
+default, the command to run the test is @command{make check}, but any
+command can be specified via the @code{#:test-command} argument.  The
+@code{#:test-command} argument expects a list containing a command and
+its arguments, to be invoked during the @code{check} phase.
+
+The Elisp dependencies of Emacs packages are typically provided as
+@code{propagated-inputs} when required at run time.  As for other
+packages, build or test dependencies should be specified as
+@code{native-inputs}.
+
+Emacs packages sometimes depend on resources directories that should be
+installed along the Elisp files.  The @code{#:include} argument can be
+used for that purpose, by specifying a list of regexps to match.  The
+best practice when using the @code{#:include} argument is to extend
+rather than override its default value (accessible via the
+@code{%default-include} variable).  As an example, a yasnippet extension
+package typically include a @file{snippets} directory, which could be
+copied to the installation directory using:
+
+@lisp
+#:include (cons "^snippets/" %default-include))
+@end lisp
+
+When encountering problems, it is wise to check for the presence of the
+@code{Package-Requires} extension header in the package main source
+file, and whether any dependencies and their versions listed therein are
+satisfied.

+Ada system.  Being an interpreter, it does not implement most representation

+with rich support for ANSI SQL (e.g., @code{INSERT...RETURNING}) including
+@acronym{UDFs, user-defined functions} and PSQL stored procedures, cursors, and
+triggers.  Transactions provide full ACID-compliant referential integrity.
+
+The database requires very little manual maintenance once set up, making it
+ideal for small business or embedded use.
+
+When installed as a traditional local or remote (network) database server,
+Firebird can grow to terabyte scale with proper tuning---although PostgreSQL
+may be a better choice for such very large environments.
+
+Firebird can also be embedded into stand-alone applications that don't want or
+need a full client & server.  Used in this manner, it offers richer SQL support
+than SQLite as well as the option to seamlessly migrate to a client/server
+database later.")
