\brief Set a global (or module) parameter.
This setting is shared by all Z3 contexts.
When a Z3 module is initialized it will use the value of these parameters
when Z3_params objects are not provided.
The name of parameter can be composed of characters [a-z][A-Z], digits [0-9], '-' and '_'.
The character '.' is a delimiter (more later).
The parameter names are case-insensitive. The character '-' should be viewed as an "alias" for '_'.
Thus, the following parameter names are considered equivalent: "pp.decimal-precision" and "PP.DECIMAL_PRECISION".
This function can be used to set parameters for a specific Z3 module.
This can be done by using <module-name>.<parameter-name>.
For example:
Z3_global_param_set('pp.decimal', 'true')
will set the parameter "decimal" in the module "pp" to true.

@ -0,0 +1,9 @@
This directory contains the "remains" of the old parameter setting
infrastructure used by Z3. Old code (mostly `smt::context`) is still
based on the front_end_params structure. However, we removed support
for the old INI file infrastructure. Instead, we have functions for
setting the fields of front_end_params using parameter sets
(params_ref). Moreover, many of the parameters in front_end_params
are now "hidden". That is, they can't be set from the command line or
using the command `set-option`.

The name of parameter can be composed of characters [a-z][A-Z], digits [0-9], '-' and '_'.
The character '.' is used a delimiter (more later).

The parameter names are case-insensitive. The character '-' should be viewed as an "alias" for '_'.
