 copies sisu output files to remote host using rsync. This requires that sisurc.yml has been provided with information on hostname and username, and that you have your "keys" and ssh agent in place. Note the behavior of rsync different if -R is used with other flags from if used alone. Alone the rsync --delete parameter is sent, useful for cleaning the remote directory (when -R is used together with other flags, it is not). Also see --scp. Alias -R

 generate examples of (naive) cgi search form for sqlite and pgsql depends on your already having used sisu to populate an sqlite and/or pgsql database, (the sqlite version scans the output directories for existing sisu_sqlite databases, so it is first necessary to create them, before generating the search form) see -d -D and the database section below. If the optional parameter --webserv=webrick is passed, the cgi examples created will be set up to use the default port set for use by the webrick server, (otherwise the port is left blank and the system setting used, usually 80). The samples are dumped in the present work directory which must be writable, (with screen instructions given that they be copied to the cgi-bin directory). Alias -F
 
-!_ --scp [filename/wildcard] <br>
+!_ --scp [filename/wildcard] \\
 copies sisu output files to remote host using scp. This requires that sisurc.yml has been provided with information on hostname and username, and that you have your "keys" and ssh agent in place. Also see --rsync. Alias -r

Alias -d
 
-!_ --sisupod <br>
+!_ --sisupod \\
 produces a sisupod a zipped sisu directory of markup files including sisu markup source files and the directories local configuration file, images and skins. Note: this only includes the configuration files or skins contained in ./_sisu not those in ~/.sisu -S [filename/wildcard] option. Note: (this option is tested only with zsh). Alias -S
 
-!_ --sisupod [filename/wildcard] <br>
+!_ --sisupod [filename/wildcard] \\
 produces a zipped file of the prepared document specified along with associated images, by default named sisupod.zip they may alternatively be named with the filename extension .ssp This provides a quick way of gathering the relevant parts of a sisu document which can then for example be emailed. A sisupod includes sisu markup source file, (along with associated documents if a master file, or available in multilingual versions), together with related images and skin. SiSU commands can be run directly against a sisupod contained in a local directory, or provided as a url on a remote site. As there is a security issue with skins provided by other users, they are not applied unless the flag --trust or --trusted is added to the command instruction, it is recommended that file that are not your own are treated as untrusted. The directory structure of the unzipped file is understood by sisu, and sisu commands can be run within it. Note: if you wish to send multiple files, it quickly becomes more space efficient to zip the sisu markup directory, rather than the individual files for sending). See the -S option without [filename/wildcard]. Alias -S
