Automatic Parameter Installation Function
1. If you install dviout with the TeX compiler, you might know the font locations and also their creation methods. In this case, Installation dviout can be simpler, if the following dviout functions are used.
When dviout is started and the initial settings are completed, if the mode remains at 0 and does not change and -TEXPK: is not defined, the install.par file is searched for in the directory containing the dviout that was started. If it exists, that file is regarded as the parameter file, read, and write these parameters to the Registry.
You can write parameters like -TEXPK: in install.par. This parameter file is only read during installation and is used for initial setting. Refer to it when creating your install program.
2. dviout can read a parameter file from Option->Read Parameters. If the name of parameter file begins with $_ such as $_myown.par, dviout also writes the parameters to the Registry when the file is read.
The lines starting with ;; or :` at the head of the file are for the explanation of the file and they are displayed when the file is reading. Other lines starting with ; are comment lines and they are ignored.
If the line starting with ;` is used, the choice to write the setting to the registry is also allowed.
