-- before you run this, put sum_list.asm in a dynamic library.

-- on OSX that means

GPG subkeys marked with the "authenticate" capability can be used for public key authentication with SSH. This is done using gpg-agent which, using the --enable-ssh-support option, can implement the agent protocol used by SSH.

Requirements

A working gpg2 setup is required. It may be possible to use gpg 1.4 but with gpg-agent compiled from gpg2. If you are using OS X 10.9 (Mavericks) then you may find the instructions [here][1] useful.

• current docs
  • query consists of one or more patterns
  • each pattern is an s-expression that matches nodes in a tree
  • expression consists of pair of parens containing:
    • node's type
    • optionally series of other s-expressions matching node's children
  • prefix a child pattern with a field name followed by a colon
  • match anonymous nodes by expressing name between double quotes
  • captures enable association of names with specific nodes in a pattern
• capture names are written after the nodes they refer to
