mails are now collected at $HOME/.pbsjobs
correct name of the server is nano, not bnl
fix bug: no more PBSSERVER, but PBS_SERVER
do not exit from a shell function, but return
allow looking the job folder directly using job id
use get_job_folder to log job path if available
A better mails message
auto parse incoming email using procmail. do not cp mails to ~/.pbsjobs
no more using settings file for pbs server management.  although this is less flexible, I didn't lose
anything I use, and this is much cleaner.
tildes into $HOME. get rid of nohup etc.
a faster and native way of counting lines
part of changes in pbs management
correct path for aliases
easy access to .dotfiles/tmp/mails.log
procmail is now managing the emails. MAILCHECK is only monitoring the log file.
this line is unnecessary if you are hashing hosts
gnome is managing ssh-agent
