The user manual for the GNOME spreadsheet.
This manual covers the concepts and use of Gnumeric, the GNOME desktop
environment's spreadsheet, including the formulas, the Gnumeric Solver
and data analyis tools.
GNU dc is a reverse-polish desk calculator which supports unlimited
precision arithmetic. It also allows you to define and call macros.
Normally DC reads from the standard input; if any command arguments are
given to it, they are filenames, and DC reads and executes the contents
of the files instead of reading from standard input. All normal output
is to standard output; all error messages are written to standard error.
