+## Import news helpers

+# Download, check integrity, uncompress and patch the source from app.src
+#
+# The file conf/app.src need to contains:
+# 
+# SOURCE_URL=Address to download the app archive
+# SOURCE_SUM=Control sum
+# # (Optional) Program to check the integrity (sha256sum, md5sum...)
+# # default: sha256

+# # (Optional) Archive format
+# # default: tar.gz
+# SOURCE_FORMAT=tar.gz
+# # (Optional) Put false if sources are directly in the archive root
+# # default: true
+# SOURCE_IN_SUBDIR=false
+# # (Optionnal) Name of the local archive (offline setup support)
+# # default: ${src_id}.${src_format}
+# SOURCE_FILENAME=example.tar.gz 
+#
+# Details:
+# This helper downloads sources from SOURCE_URL if there is no local source
+# archive in /opt/yunohost-apps-src/APP_ID/SOURCE_FILENAME
+#
+# If in SOURCE_URL the key __APP_VERSION__ is in, it is replaced by the version
+# from the manifest.
+#
+# Next, it checks the integrity with "SOURCE_SUM_PRG -c --status" command.
+#
+# If it's ok, the source archive will be uncompressed in $dest_dir. If the
+# SOURCE_IN_SUBDIR is true, the first level directory of the archive will be
+# removed.
+#
+# Finally, patches named sources/patches/${src_id}-*.patch and extra files in
+# sources/extra_files/$src_id will be applied to dest_dir
+#
+#
