# -gsrc:

Define the way to operate the graphic editor when an included graphic is pointed in the preview window as in the similar way in source specials. For example
.ps.eps=c:\usr\local\bin\psedit.exe^s"%n";.bmp=mspaint^s"%s"
Indicate the extensions of graphic files and the corresponding operations as above with the separator ;.
The extensions are indicated including the last . and they may be gathered if they correspond to the same operation. Then indicate the operation followed by =.
In the format to indicate the operation (as in the case of -src:) , ^s is the separator between the program to be executed and its parameter, %s is the corresponding graphic file and %n is the filename without extension.
The graphic file whose extension is not defined here is ignored for the operation.
