 dsmci
 
-an scripting collection for backup up large filesysteme with parallel tree walks and backup jobs
+a script for backup up large filesysteme with parallel tree walks and backup jobs
 using intially IBM TSM / ISP and the "dsmc i" command
 
- initially there were three flavours
+there are two versions of the script
+- `dsmci.pl` has passed some tests and is in use at GWDG
+- `dev-dsmci.pl` contains some new functions, but is in development
+
+**Important:**
+
+The newer versions of dsmci.pl uses the module "File::Find::Rule". This seems not to be part of all perl installations so
+you may need to install it manually like this
+  cpan -i File::Find::Rule
+
+**Even if `dsmci.pl` has passed some tests and is in use, we do not assume no guarantee or liability for errors or omissions.**
+
+Contributions are welcome :-)
+
+*former develepment:*
+
+the project started as a collection of scripts, initially there were three flavours
 - bash       (for Linux only, deprecated, abandomed)
 - perl       (for Linux and Windows, in develeopment)
 - powershell (for windows only, abandomed)
 
-now there are different versions inside the perl implementation
+then there were also different versions inside the perl implementation
 - dsmcis.pl     the simple approach working just one level below the given start folder, "S" is for "simple"
 - dsmci.pl      an approache allowing to set the depth to dive in before doing the parallel processing
 - dsmciFD.pl    an approche diving down to the deepest folder level and backup up *all* folders in parallel, "FD" is for "full depth"
 
-=> all versions are tested and work, but NO guarantee is given :-)
 
-Important:
-The newest version of dsmci.pl uses the module "File::Find::Rule". This seems not to be part of all perl installations so
-you may need to install it manually like this
