I missed two library dependancies for pushimage when I moved it from crostools to src/script. Moving them now.

# TimeStamp < begin | end | done > [ section ]
|
||||
#+ DESCRIPTION
|
||||
#+ TimeStamp begin is run at the beginning of the script to display a
|
||||
#+ 'begin' marker and TimeStamp end is run at the end of the script to
|
||||
#+ display an 'end' marker.
|
||||
#+ TimeStamp will auto-scope to the current shell or you can optionally
|
||||
#+ pass in a second argument as a section identifier if you wish to track
|
||||
#+ multiple times within the same shell.
|
||||
#+
|
||||
#+ For example, if you call TimeStamp begin and end within one script and then
|
||||
#+ call it again in another script (new shell), you can just use begin and end
|
||||
#+ But if you want to call it twice within the same script use it like this:
|
||||
#+
