Subject: boinc-app.eclass: better wrapper install function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

"dowrapper" had too much magic: it relied on specifically files being
present in ${FILESDIR}, which is just… wrong.

It will burn in flames without any backwards compatibility. New
"boinc_install_wrapper" function replaces it.

-# @FUNCTION: dowrapper
-# @USAGE: <app> [more apps...]
+# @FUNCTION: boinc_install_wrapper
+# @USAGE: <bin> <job> [new name]
 # @DESCRIPTION:
 # This function provides a uniform way to install wrapper applications
 # for BOINC projects. It makes symlinks to the BOINC wrapper and also
 # installs respective job.xml files.
 #
-# When sci-misc/boinc-example-1.0 calls `dowrapper boinc-example` it:
+# When `dowrapper boinc-example_wrapper A.xml B.xml` is called, it:
 #
-# 1. Installs boinc-example_job_1.0.xml from ebuild's files/ directory
-#    to project's root directory
+# 1. Installs A.xml in the project's root directory, renaming it to B.xml
 #
-# 2. Installs boinc-example_wrapper_1.0 symlink, which points
-#    to /usr/bin/boinc-wrapper, to project's root directory
+# 2. Installs boinc-example_wrapper symlink, which points
+#    to /usr/bin/boinc-wrapper, in the project's root directory
 #
 # Example:
 # @CODE
 # src_install() {
 # 	meson_src_install
 #
-# 	dowrapper boinc-example boinc-sample
+# 	boinc_install_wrapper boinc-example_wrapper "${FILESDIR}"/job.xml
 #	doappinfo "${FILESDIR}"/app_info_${PV}.xml
 # }
 # @CODE
 #
 # Keep your job.xml files in sync with app_info.xml!
