* main.c (captured_main): Define struct cmdarg. Change type of cmdarg. Add new options --eval-command and alias -ex. Adjust --command to use the new struct cmdarg. Execute commands given with --eval-command. (print_gdb_help): Add new options --eval-command, -ex and mention -x. docs/ * gdb.texinfo (Choosing files): Add --eval-command.
