*
*
* The easiest way to generate code is to use the FHIR Validator, which can generate java classes for profiles
* using this code. Parameters:
*
*
* -codegen -version r4 -ig hl7.fhir.dk.core#3.2.0 -profiles http://hl7.dk/fhir/core/StructureDefinition/dk-core-gln-identifier,http://hl7.dk/fhir/core/StructureDefinition/dk-core-patient -output /Users/grahamegrieve/temp/codegen -package-name org.hl7.fhir.test
*
*
* Parameter Documentation:
* -codegen: tells the validator to generate code
* -version {r4|5}: which version to generate for
* -version {r4|5}: which version to generate for
* -ig {name}: loads an IG (and it's dependencies) - see -ig documentation for the validator
* -profiles {list}: a comma separated list of profile URLs to generate code for
* -profiles {list}: a comma separated list of profile URLs to generate code for
* -output {folder}: the folder where to generate the output java class source code
* -package-name {name}: the name of the java package to generate in
*
*
* options
* -option {name}: a code generation option, one of:
*
*
* narrative: generate code for the resource narrative (recommended: don't - leave that for the native resource level)
* meta: generate code the what's in meta
* contained: generate code for contained resources
* contained: generate code for contained resources
* all-elements: generate code for all elements, not just the key elements (makes the code verbose)
