SYNOPSIS

       samidare [OPTION]...  [URL]...

DESCRIPTION

       Samidare  checks  web  page  updates.  It takes a list of URLs in a configuration file, config.yml, and checks last update time of them.  A
       HTML file, latest.html, is generated to show the updates.

       -v, --verbose
	      specify verbose mode.

       -n, --no-check
	      don't check web.	output generation only.

       -f, --force

	      specify output html filename.

       --output-lirs=filename
	      specify output lirs filename.

       -T, --template=filename
	      specify template filename.

       --remove-entry
	      remove entry of pages specified by URLs.

       --diff-content
	      show difference of recent two files of specified URLs.

USAGE

       samidare is configured by "config.yml" and "t.latest.html" by default.

       samidare generates "latest.html" and "sites.lirs.gz"

       samidare uses "status.rm" and "tmp" to record status of pages.

       "config.yml" is a configuration file in YAML format.  See EXAMPLES section for its content.

       "t.latest.html" is a template file.  In the file, "data" variable can be used.  See the document of htree library for template directives.

       So you can run samidare as follows.

	 % cd $HOME
	 % mkdir samidare
	 % cd samidare
	 % vi config.yml
	 % vi t.latest.html	       # optional
	 % samidare
	 % w3m latest.html	       # view the result

       If you want to publish the result, use symbolic link to latest.html and sites.lirs.gz as follows.

	 % mkdir public_html
	 % mkdir public_html/samidare
	 % cd public_html/samidare
	 % ln -s ../../samidare/latest.html .
	 % ln -s ../../samidare/sites.lirs.gz .

EXAMPLES

       The configuration file is described in YAML format.

       The simplest configuration is list of URLs as follows.

	 - http://www.example.org/blog/
	 - http://www.example.net/

FILES

       "config.yml" and "t.latest.html" is configuration file.

       "latest.html" and "sites.lirs.gz" is output.

       "status.rm" and "tmp" is used by samidare internally.

SECURITY

       samidare stores pages in tmp directory.	If it is published via your web server, XSS (cross site scripting) is possible.  So the  directory
       should not be published.
