software used by NsCDE is:

     *  Korn Shell 93. All shell script routines inside configuration, helper
       scripts and FvwmScript helpers are written with ksh. It is not sure if
       pdksh can be drop in replacement, but in tests on Arch Linux with mksh
       it became clear that mksh cannot replace Korn Shell. Korn Shell is
       available and it is free.

     *  Xorg utils (Fedora/CentOS RPM xorg-x11-utils) - xdpyinfo, xprop ...

     *  Util xdotool - only if FVWM is not patched with WindowName patch for
       the FvwmButtons

     *  ImageMagick - really needed.

     *  Xscreensaver - optional, but Screen Style Manager will not work
       without it. Something needs to be installed for locking the screen.

     *  cpp - C preprocessor for xrdb functionality - for X resources
       integration. Used by xrdb(1).

     *  xorg-x11-server-utils (CentOS, Fedora name) - xrdb, xset, xrefresh
       mandatory for startup, some style managers and menus.

     *  python-yaml - needed for python part of the color theme management
       and for Gtk+Qt integration.

     *  PyQt4, PyQt5 or possibly python3-qt4, python-qt5 or python3-qt5 or ...
       This is unfortunate dependency which is further dependent on Qt
       libraries. NsCDE tries to have as less as possible dependencies,
       specially indirect (dependencies of dependent dependencies of
       dependencies ...). Gtk/Qt integration is borrowed from CDEtheme
       Motif/CDE theme project and adapted for use with FVWM (instead of
       heavy Xfce dependency) or standalone engine. In part of the Theme.py
       code, some png pixmaps are cut and colored with functions from this
       API. With present job and lack of time, there was no time to do this
       without PyQt5 or PyQt4 for the first public release.

     *  Gtk2, Gtk3, Qt4, Qt5, qtconfig-qt4, qt5ct, qt5-qtstyleplugins
       (optional) There is a great chance this libraries and some usefull
       programs using them are already installed on user's system. If Gtk and
       Qt integration is activated in [70]Color Style Manager, there is no
       point not to have it installed.

         Notice about Qt4 and Qt5: qt4-config (or qt-config) and qt5ct:
       Although colors will be applied, for font setting to take effect,
       qtconfig-qt4 (or qtconfig) must be run, something changed back and
       forth, and then applied/saved - no matter that you will see fonts of
       your choice already selected. This can be considered a bug. Same goes
       for Qt5.

         Notice about Qt5: QT_QPA_PLATFORMTHEME environment variable must be
       set, and be set to qt5ct value in order to run qt5ct configurator.

     *  Recommended fonts for as close as possible CDE look are DejaVu Serif
       for variable, and DejaVu Sans Mono for monospaced fonts. Check should
       be made if this fonts are installed on the system. For Solaris CDE
       look, Lucida Sans and monospaced Lucida Sans Typewriter should be
       installed, selected and used instead. (optional)

     *  Open Motif 2 libraries for some programs, although it is not used in
       any part of the NsCDE. (optional)

     *  Stalonetray for "tray" facility (optional)

     *  XSETTINGS xsettingsd daemon for theme and X settings dynamic
        management (optional)

     *  xterm

     *  python3 (FVWM)

     *  python34-pyxdg or python3-pyxdg or python36-pyxdg or ... (FVWM)

     *  libstroke (FVWM)

     *  perl-File-MimeInfo (on some platforms and some fvwm packages)
