Hint for users of AdaControl (-m, -o, -r and -w options)

Hint for users of AdaControl (-m, -o, -r and -w options)

[Yannick Duchêne (Hibou57)]

Hi happy AdaControl users,

Don't know if this was already noticed somewhere, but I've just noticed  
some care must taken when one use the “-w“ in a specific circumstance:  
this option direct the adactl command to overwrite the output file  
specifies by the “-o <file>” option. If you do so *with* the “-r” option  
*without* the “-m” option, you will a get an output file looking like  
truncated. The output file will be overwritten for each processed units  
spec' and body. When the “-m” option is specified, this undesired behavior  
is not exposed.

Conclusion: if you use the options “-o” “-r” and “-w” all together, always  
serve it with an “-m” option (this will also prevent you from erroneously  
suspecting a bug in adactl ;-) ).

Oh, shit! I wanted to say AdaDep (sorry for the wrong thread's title). In  
the above, replace all adactl occurrences, by adadep (that's me, which is  
buggy). Fixed in the quote.

I think I overlooked this issue. This is not the goal of the -m option.
The intended behaviour is that without -m you get a listing for each
unit, and with -m all the listings are merged. I noticed also that -m is
poorly documented...

I'll try to find the time to fix that (possibly in the plane between
Paris and Stockholm!)
