+# vim-gdb
+
+vim-gdb integrates gdb running in `:terminal` into vim.
+
+
+## Usage
+
+Run the command `:Vimgdb [args]`, for example `:Vimgdb --args /bin/ls -l`. This
+will open a new window with gdb. The current window will be used to display the
+source files when gdb stops.

+#!/bin/bash
+
+export VIMGDB_DIR=$(dirname "$0")
+export VIMGDB_SESSION_ID="$1"
+shift
+exec gdb -x "$VIMGDB_DIR/gdbinit" "$@"
