"""
Retrieves slap partition parameters, and makes them available to other
buildout section in various ways, and in various encodings.
Populates the buildout section it is used in with all slap partition
parameters.
Input:
url
Slap server url.
Example:
${slap-connection:server-url}
key & cert (optional)
Path of files containing key and certificate for secure connection to
slap server.
Example:
${slap-connection:key-file}
${slap-connection:cert-file}
computer
Computer identifier.
Example:
${slap-connection:computer-id}
partition
Partition identifier.
Example:
${slap-connection:partition-id}
unsafe (optional, 0 by default)
Enables formats which are unsafe when represented back into a buildout
text file. Set to 0 to explicitly disable unsafe formats, any other
integer value to enable them.
Output:
One key per supported serialisation format, with all partition parameters
serialised in that format as values and format's name.
Also, one key per partition parameter, prefixed with serialisation format
followed by a dot. Example:
json = {"foo": "bar"}
json.foo = "bar"
Supported serailisation formats:
json (safe)
JavaScript Object Notation
str (unsafe)
Python string representation.
