good practices

- emphase the relevant data:
* bold different words in repetitive items
--- habla con madre
--- habla son madre

* capitalize different letter in similar names
--- pay_wta_voms and pay_wtK_voms

- build a system to allow tracking of
* information --- in a file put the info and its source
* documentation --- use the Tracking changes
* files --- filename f=wtk_viewVoucherPrint_err379_`hostname`.txt
