Flycheck provides fully-automatic, fail-safe, on-the-fly background syntax
checking for over 30 programming and markup languages with more than 70
different tools.  It highlights errors and warnings inline in the buffer, and
provides an optional IDE-like error list.")

database.  SQLite is used as backend.  This library imposes some restrictions
on what kind of objects can be stored; it isn't intended to store arbitrary
objects.  All objects have to share a common superclass and subclasses cannot
add any additional instance slots.")

Epkg itself is not a package manager.

Getting a local copy:

@example
git clone https://github.com/emacsmirror/epkgs.git ~/.emacs.d/epkgs
cd ~/.emacs.d/epkgs
git submodule init
git config --global url.https://github.com/.insteadOf git@@github.com:
git submodule update
@end example

Some submodule may be missing.  In this case Git will prompt for a GitHub user
name and password.  To skip it press a @key{Return} key.

You could get a Epkg package list by invoking @code{epkg-list-packages} in
Emacs.")

stepping through the expansion of macros in Emacs Lisp source code.  It lets
you see exactly what happens at each step of the expansion process by
pretty-printing the expanded forms inline in the source buffer, which is
temporarily read-only while macro expansions are visible.  You can expand and
collapse macro forms one step at a time, and evaluate or instrument the
expansions for debugging with Edebug as normal (but see “Bugs and known
limitations”, below).  Single-stepping through the expansion is particularly
useful for debugging macros that expand into another macro form.  These can be
difficult to debug with Emacs’ built-in macroexpand, which continues expansion
until the top-level form is no longer a macro call.")
