 VALET allows package definitions in a variety of formats (XML, JSON, YAML) but YAML tends to be the simplest format so we will use it here. VALET allows package definitions in a variety of formats (XML, JSON, YAML) but YAML tends to be the simplest format so we will use it here.
 +
 +==== Package section ====
 +
 +The //package section// of the definition file includes items that apply to all versions/variants of the software:
 +<code yaml>
 +quantum-espresso:
 +    prefix: /home/user/sw/quantum-espresso
 +    description: quantum-espresso
 +    url: "https://www.quantum-espresso.org/"
 +</code>
 +The //package identifier// is the top-level key in the document — ''quantum-espresso'' — and the value of ''$QE_BASEDIR'' is the value of the ''prefix'' key in this section.  The URL and description are information taken from the official quantum-espresso web site.
 +
 +==== Versions ====
 +
 +The ''versions'' key is used to provide a list of the versions/variants of the software:
 +<code yaml>
 +quantum-espresso:
 +    prefix: /home/user/sw/quantum-espresso
 +    description: quantum-espresso
 +    url: "https://www.quantum-espresso.org/"
 +    
 +    versions:
 +        "v7.3":
 +            description: compiled with Open MPI, Intel compilers, MKL, ScaLAPACK
 +            dependencies:
 +                - openmpi/4.1.5:intel-oneapi-2023
 +               
 +</code>
 +
 +<WRAP center round tip 80%>
 +The version identifier ''v7.3'' is inferred to be the path prefix to the version in question here.  The package's prefix (''/home/user/sw/quantum-espresso'') with the version identifier appended (''/home/user/sw/quantum-espresso/v7.3'') is implicit.
 +
 +The implicit behavior is overridden by providing a ''prefix'' key in the version definition:  a relative path is appended to the package's prefix, an absolute path is used as-is.

 +
 +It is a good idea to specify which version definition should act as the default.  This yields the following package definition file
 +
 +<file yaml quantum-espresso.vpkg_yaml.darwin>
 +quantum-espresso:

 +    description: quantum-espresso

 +</file>
 +
 +saved at ''$VALET_PKG_DIR/quantum-espresso.vpkg_yaml''.
 +
 +==== Checking the definition file ====
 +
 +The package definition file can be checked for proper syntax using the VALET command ''vpkg_check'':
 +<code bash>
 +[user@login00.darwin ~]$ vpkg_check "$VALET_PKG_DIR/quantum-espresso.vpkg_yaml"
 +/home/user/.valet/quantum-espresso.vpkg_yaml is OK
 +[quantum-espresso] {
 +  contexts: all
 +  actions: {
 +    QUANTUM_DASH_ESPRESSO_PREFIX=${VALET_PATH_PREFIX} (contexts: development)
 +  }
 +  https://www.quantum-espresso.org/
 +  quantum-espresso
 +  prefix: /work/user/sw/quantum-espresso
 +  source file: /home/user/.valet/quantum-espresso.vpkg_yaml
 +  default version: quantum-espresso/v7.3
 +  versions: {
 +    [quantum-espresso/v7.3] {
 +      contexts: all
 +      dependencies: {
 +        openmpi/4.1.5:intel-oneapi-2023
 +      }
 +      compiled with Open MPI, Intel compilers, MKL, ScaLAPACK
 +      prefix: /work/user/sw/quantum-espresso/v7.3
 +    }
 +  }
 +}
 +
 +</code>
 +The file had no errors in its YAML syntax.  Notice also that the standard path (''bin'') is found and noted by VALET!
 +
 +==== Runtime environment ====
 +
 +To load **quantum-espresso** 7.3 into the runtime environment, the ''vpkg_require'' command is used:
 +<code bash>
 +[user@login00.darwin ~]$ vpkg_require quantum-espresso/v7.3
 +Adding dependency `binutils/2.35.1` to your environment
 +Adding dependency `gcc/12.2.0` to your environment
 +Adding dependency `intel-oneapi/2023.0.0.25537` to your environment
 +Adding dependency `ucx/1.13.1` to your environment
 +Adding dependency `openmpi/4.1.5:intel-oneapi-2023` to your environment
 +Adding package `quantum-espresso/v7.3` to your environment
 +[user@login00.darwin ~]$ which pw.x
 +~/sw/quantum-espresso/v7.3/bin/pw.x
 +</code>
 +
 +===== Scaling =====
 +
 +This is the wall time for the structure relaxation of silicon with respect to the number of cores. The wall time decreases with an increased number of cores.
