HelpSetMaker allows to run an export via the command line. You give root directory and output mode as comma-seperated parameters to the "--make" or "-m" option:
java -jar helpsetmaker.jar --make /home/dh/helpsetmaker/doc/online,HTML4
Known modes are:
HELPSET - Java HelpSet
HTML4 - Hierarchy of HTML files to be presented in a browser
HTML4BIGPAGE - One single HTML page containing all pages
LATEX - LaTeX source file with pictures directory
Default setting is HTML4, detection is case insensitive. If an unknown mode is given, nothing is produced.
In batch exporting mode, HelpSetMaker does not open any window. The program stops immediately after finishing the exporting task.
