This version of zsh has been compiled with support for maildir
folders in MAIL and MAILPATH.

How to use the zsh-dbgsym package
---------------------------------
To install the zsh-dbgsym package you first need to add the APT
repository for debug packages. Since this APT repo is rather huge, but
seldomly needed, it's usually not available on your average Debian
mirror. As root or with sudo edit the file /etc/apt/sources.list (or
add a new file /etc/apt/sources.list.d/dbgpkg.list) with the following
contents:
deb http://debug.mirrors.debian.org/debian-debug/ <your-release>-debug <your-archive>
and replace <your-release> and <your-archive> with the according
values for your installation. E.g. on Debian Buster it probably looks
like this:
deb http://debug.mirrors.debian.org/debian-debug/ buster-debug main
After having edited the file, run "apt update" with root
permissions (e.g. with sudo).
See https://wiki.debian.org/AutomaticDebugPackages and
https://michael-prokop.at/blog/2017/05/26/the-newinstretch-game-dbgsym-packages-in-debianstretch/
for details.
Afterwards execute in the first terminal:
sudo apt install zsh-dbgsym
apt source zsh
cd zsh-*
In the second terminal invoke 'zsh -f' (or drop the '-f' if you
don't want to start with a clean Zsh session). Execute all the
relevant steps right *before* you can trigger the problem you
want to inspect using gdb.
Return to the first terminal where you're standing in Zsh's
source directory. Identify the process id of the Zsh instance
you want to debug ("ps aux | grep '[z]sh'") and use it for $PID.
Then execute:
gdb $(find . -type d -printf '-d %p ') attach $PID
Now you can use the usual gdb commands like step / continue / ...
to debug the Zsh process at source level.

Load-path for functions from other packages
-------------------------------------------
In response to #620452, the zsh-binary from Debian's zsh package started to
provide two entries to $fpath (the search path for loadable functions) for
other packages to drop function files into:
- /usr/share/zsh/vendor-completions for functions that add functionality to
zsh's function based completion system (compsys)
- /usr/share/zsh/vendor-functions for all other functions
If you maintain another Debian package that wants to add functions to zsh's
function load-path, please use the those conventions when installing function
files.

Patch series management functionality
-------------------------------------
vcs_info is a zsh contributed function for showing information from version
control systems (git, hg, svn, ...) at the prompt.
Maintainers of Debian packagers may find it useful to enable vcs_info's patch
series functionality when managing their packages' patch series. See
/usr/share/doc/zsh/examples/Misc/vcs_info-examples for examples and the
vcs_info section in the manual[1] for reference.
