How do I do it? I know that I can write a form to init-file (or custom-file). Are there any facilities in Emacs which support that? Or should I write them myself? A cursorty look at custom-save-all suggests that there are no high-level functions to "save one particular thing to (custom-file)". (I could make my variable customizable and use custom-save-variables, but I do not want to do that - I feel this is too heavy-weight for just one variable, and I don't even know whether my potential users know/use/like the customization stuff messing around with their init file.) Any ideas? -- Marcin Borkowski http://mbork.pl
