+# If GZIP_COMPRESSION is set to "yes" then the static css, js, and html files will be compressed with gzip before added to the espfs image
+# and will be served with gzip Content-Encoding header.
+# This could speed up the downloading of these files, but might break compatibility with older web browsers not supporting gzip encoding
+# because Accept-Encoding is simply ignored. Enable this option if you have large static files to serve (for e.g. JQuery, Twitter bootstrap)
+# By default only js, css and html files are compressed.
+# If you have text based static files with different extensions what you want to serve compressed then you will need to add the extension to the following places:
+# - Add the extension to this Makefile at the webpages.espfs target to the find command
+# - Add the extension to the gzippedFileTypes array in the user/httpd.c file
+#
+# Adding JPG or PNG files (and any other compressed formats) is not recommended, because GZIP compression does not works effectively on compressed files.
+
+#Static gzipping is disabled by default.
+GZIP_COMPRESSION = yes
+
+# If COMPRESS_W_YUI is set to "yes" then the static css and js files will be compressed with yui-compressor
+# This option works only when GZIP_COMPRESSION is set to "yes"

+#Disabled by default.

+#If USE_HEATSHRINK is set to "yes" then the espfs files will be compressed with Heatshrink and decompressed
+#on the fly while reading the file. Because the decompression is done in the esp8266, it does not require
+#any support in the browser.
