Dependencies

[2] 3TZGWQHO Allow downloading file by filename
[3] MAOFG2TD * Allow omitting the product number if there is only one product in a
[4] 7UHHF564 Security: Also check paths in the web server
[5] LBNVQXUB * Build the /build stuff in a separate controller.
[6] PMNWRTGJ Add multiple output support
[7] OD5FSS5A * Quick hack to allow viewing of dependency graphs (via nix-store -q
[8] GJFYEU3S * Nix now stores logs by default as bzip2, make sure the build page uncompresses before showing.
[9] EFWN7JBV * Added a status page that shows all the currently executing build steps.
[10] 5NO7NCKT * Refactoring.
