Hi,
while reading the docs about job concurrency and such I found some
conflicting statements which should be fixed IMO to make it more
consistent.
1. What to do to enable concurrent jobs

I guess I am not the only one who has to read those paragraphs
several times to understand it. I think they can be updated a bit to
make it more readable and better understandable.
"The downside is that it can be a bit tricky to set it up for the
first time as you need to set the concurrency in at least five
different places."
I consider this wrong: Its *at least* 4 places in *one* config file:
bacula-dir.conf: Director{}, Job{}, Client{}, Storage{}
And telling here that its only one file you have to modify would
help to understand more quickly.
later:
"Below is a super stripped down bacula-dir.conf file showing you the
four places where the the file has been modified..."
So fixing this to read
"The downside is that it can be a bit tricky to
set it up for the first time as you need to set the concurrency in
at least four different places in the Director's conf file (bacula-dir.conf).
"
makes this sentence quiet needless because it sounds much like what
is written later on.
So attached is a patch to docs/manual/tips.tex to "fix" this.

\index[general]{Concurrent Jobs}
Bacula can run multiple concurrent jobs, but the default configuration files
-are not set to do so. Using the {\bf Maximum Concurrent Jobs} directive, you
-have a lot of control over how many jobs can run at the same time, and which
-jobs can run simultaneously. The downside is that it can be a bit tricky to
-set it up for the first time as you need to set the concurrency in at least
-five different places.
-
-The Director, the File daemon, and the Storage daemon each have a {\bf Maximum
-Concurrent Jobs} directive that determines overall number of concurrent jobs
-the daemon will run. The default is one for the Director and ten for both the
-File daemon and the Storage daemon, so assuming you will not be running more
-than ten concurrent jobs, the only changes that are needed are in the
-Director's conf file (bacula-dir.conf).
-
-Within the Director's configuration file, {\bf Maximum Concurrent Jobs} can be
-set in the Direct, Job, Client, and Storage resources. Each one must be set
-properly, according to your needs, otherwise your jobs may be run one at a
-time.
+do not permit this. Using the {\bf Maximum Concurrent Jobs} directive, you
+can configure how many and which jobs can be run simultaneously.
+The Director's default value for {\bf Maximum Concurrent Jobs} is "1".
+
+Note: To set it up initially you need to set {\bf Maximum Concurrent Jobs} in
+at least four different places in the Director's configuration file
(bacula-dir.conf)
+to make it work: The Director, Job, Client, and Storage resources.
+
+Additionally the File daemon, and the Storage daemon each have their own {\bf
Maximum
+Concurrent Jobs} directive that sets the overall maximum number of concurrent
jobs
+the daemon will run.
+The default for both the File daemon and the Storage daemon is "10".
For example, if you want two different jobs to run simultaneously backing up
the same Client to the same Storage device, they will run concurrently only if
