# lws minimal secure streams policy2c
This application parses a JSON policy passed on stdin and emits the
equivalent of it in C structs ready for compilation.
This is useful in the case your platform doesn't use a dynamic JSON
policy and is space-constrained, you can still form and maintain the
policy in JSON, but with this utility convert it into compileable C.
**Notice** this depends on LWS_ROLE_H1, LWS_ROLE_H2, LWS_ROLE_WS and
LWS_ROLE_MQTT build of lws, since it has to be able to work with any kind
of policy content.
## build
```
$ cmake . && make
```
## usage
