Let me step up the volume a little bit:

 ANOUNCEMENT!
   pcb and gschem can now handle libraries with more than one level
   of subdirectories.

My footprint lib is organized like this:

footprints
├── connectors
│   ├── coaxial
│   ├── DVI
│   ├── JAE_IL-G
│   ├── LEMO
│   ├── pin_headers
│   ├── RIACON
│   ├── RJ45
│   ├── SCSI
│   ├── subD
│   └── XLR
├── discretes
│   ├── capacitors
│   ├── diodes
│   ├── inductors
│   ├── potentiometers
│   ├── resistors
│   └── varistors
├── generic
│   └── DIP
├── logos
├── mechanical
│   ├── blocks
│   ├── boxes
│   └── holes
├── misc
├── specific
└── switches

Traditionally, this needed a library search string that includes all the
dirs below $HOME/geda/footprints :

library-newlib = ~/geda/kai_martin_knaak/footprints/connectors:~/geda/
kai_martin_knaak/ footprints/discretes:~/geda/kai_martin_knaak/footprints/
generic:~/geda/kai_martin_knaak/footprints/mechanical:~/geda/kai_martin
_knaak/footprints/potentiometers:~/geda/kai_martin_knaak/footprints/logos:
~/geda/kai_martin_knaak/footprints/misc:~/geda/kai_martin_knaak/footprints/
switches:~/geda/kai_martin_knaak/footprints/specific:.

Note, that the string contains close to 512 characters. This is no 
coincidence, since pcb cut the string at about this margin on save. 

With Rolands patches my footprint lib becomes accessible to pcb with 
this single line:
 library-newlib = ~/geda/gedasymbols/www/user/kai_martin_knaak/footprints:.

Roland also fixed the footprint chooser dialog to show an expandable tree
rather than a flat list. Library handling in had similar quirks. Since his
patches the symbol chooser dialog shows a proper tree, too.

Cheers to him!
