+name: seergdb
+title: Seer
+summary: A GUI frontend to gdb
+description: |
+  Seer is a graphical frontend to the GDB debugger that provides a rich
+  development environment for debugging programs, including:
+
+  - Source code browsing and breakpoint management
+  - Variable inspection and modification
+  - Stack frame navigation
+  - Memory inspection
+  - Assembly view
+  - Register view
+
+  Seer runs the host's own gdb and attaches to/launches the programs you
+  ask it to debug, so this snap uses classic confinement: it needs
+  unrestricted access to the filesystem (to find source and binaries
+  anywhere on the system) and to ptrace arbitrary processes, neither of
+  which is possible from a strictly confined snap.
