A new file type (.demo) in the configs tree is supported by the linuxcnc
script and the configuration selector (pickconfig.tcl). A .demo file
must be executable and is typically implemented as a shell script that
invokes an application with appropriate parameters.
This facility makes it possible to demonstrate apps related to linuxcnc
using pickconfig without starting linuxcnc or requiring a complete ini
file.
Thanks to Chris Morley for suggestion
Details:
Modify pickconfig to support .demo files
Use noforcecopy for .demo files which should not be copied to
a user dir
Provide .demo apps for halrun,info,parport,xhc-hb04
Provide .demo apps for gladevcp,pyvcp
New script: linuxcnc_var and removal of several scripts/*.in.
Rename latency scripts for consistency (and reduce merge overwrites).
Remove latencyplot from menu.
Moved gladevcp demo apps from root/gladevcp to configs/apps/gladevcp
The root/gladevcp/ examples were orphans and didn't work with
the configuration selector
Change .py files so persistent files are named .save instead of
.ini to avoid conflict with .ini files which the configuration
selector presumes are working configs.
Rebranding in some py files
Some clarifications within copied README files
Consolidate by-widgets dir
Update docs
New doc for configuration selector (needs formatting)
Update for configs tree rearrangement
Rename 2 non working sim .ini files to .ini.notworking
this includes the main script, some of the GUIs, the Python module,
the Tcl package, some image fies.
On a sim system, axis, tkemc, xemc all start. runtests pass.
a system with realtime wasn't yet tested.
packaging probably requires additional changes and was not yet tested.
