function st

Translates a string when some systems are not available.

Used during the install process, when database, theme, and localization system is possibly not yet available.

Use t() if your code will never run during the Backdrop installation phase. Use st() if your code will only run during installation and never any other time. Use get_t() if your code could run in either circumstance.
