The programmer can not Xbe held liable for any incurred damages due to the use of this software. X XYou are encouraged to distribute this package freely. This package is Xhowever not to be sold (minor transfer costs excepted) or included in Xany commercially sold software package (if you want to do this anyway, Xcontact me (address below), and we'll work something out). X XIf you distribute it, please leave the package in tact. If you have some Ximportant changes that might be usefull to the rest of the world, contact Xme instead. X X-------------------------- SYSTEM REQUIREMENTS ------------------------------- X XA ".forward" file (or equivalent) mechanism for forwarding mail, *grep or Xequivalent. X XThe most important system calls that need to be supported (among others): Xfork(),read(),write(),dup(),wait(),pipe(),getpwent() X XFor a more complete list of all library references see "includes.h" X X------------------------------ DESCRIPTION ----------------------------------- X XThe procmail mail processing program. (v2.02 1991/06/12) X XCan be used to create mail-servers, mailing lists, sort your incoming mail Xinto separate folders/files (real convenient when subscribing to one or more Xmailing lists), preprocess your mail, or selectively forward certain incoming Xmail automatically to someone. X XFor installation instructions see the INSTALL file. X X---------------------- X XAlthough I can't guarantee that the procmail program will perform as Xrequired, I must say that I made the utmost effort to make procmail as Xrobust as any program can be (every conceivable system error is caught *and* Xhandled). X Xprocmail was designed to deliver the mail under the worst conditions X(file system full, out of swap space, process table full, file table full, Xmissing support files, unavailable executables; it all doesn't matter). XShould (in the unlikely event) procmail be unable to deliver your mail Xsomewhere, the mail will bounce back to the sender. X XFor a more extensive list of features see the FEATURES file. X XHowever, as with any program, bugs can not be completely ruled out. XI tested the program extensively, and believe it should be relatively Xbug free (no known bug at the time). Should, however, anyone find any Xbugs (highly unlikely :-), I would be pleased (well, sort of :-) to hear Xabout it. Please send me the patches or bug report. XI'll look at them and will try to fix it in a future release. X(BTW, if you should find any spelling or grammar errors in these files, Xit's not priority one, but if you were sending me mail anyway, don't hesitate Xto point them out to me; I like correct English just as much as you do). X XPlease note that this program essentially is supposed to be static, that Xmeans no extra features (honouring the *NIX spirit) are supposed to be Xadded (though any usefull suggestions will be appreciated and evaluated if Xtime permits). X XCheers, X Stephen R. van den Berg at RWTH-Aachen, Germany. X XInternet E-mail: berg@messua.informaik.rwth-aachen.de X berg@physik.tu-muenchen.de X XOr: P.O.Box 21074 X 6369 ZG Simpelveld X The Netherlands X X---------------------- X XP.S. I don't mind if you feed the program files through your favourite C X beautifier first, so any patches need not necessarily be from the X original sources; I apply these patches by hand anyway.

I know it's unconventional, Xbut it's my standard format. If you don't like it, feed it through your Xfavourite C beautifier. X XYes, I do have my reasons for formatting it this way: X1. consistent, functional indenting X2. I got used to it X3. the C compiler doesn't mind at all X4. I get more program text on my screen when editing, hence I don't have to X scroll as often to see other parts of the program while working, (you won't X believe this, I know) and therefore it helps to get a better overview of X the program X5. I hate it when I have to scroll back the screen those 5 lines just to see X the top of the loop (and then back down to look at the end again, etc.) X XAnd, now don't start flaming me about "bad practice", I don't consider this Xformatting method bad practice (it's properly indented). X XI consider "bad practice" to be unportable or non-ANSI code, which my code is Xcertainly not.
