The default is \fBComics\fP. .TP \fB\-\-baseurl=\fP\fIPATH\fP Specifies the base URL for output events. The default is a local file URI. .TP \fB\-a\fP, \fB\-\-all\fP Traverses all available strips backwards from the current one. This can be useful you want a full collection of a new comic strip, or update an existing one where files are missing. . Catchups can start at a specific strip by using the index syntax, see the .B INDEX SYNTAX and .B SPECIAL SYNTAX sections for more information. This is useful when you missed some days and want only to download the missing files. To make this task easy, the traversal ends at the first existing image file when starting from an index (excluding the index itself). .TP \fB\-h\fP, \fB\-\-help\fP Output brief help information. .TP \fB\-l\fP, \fB\-\-list\fP List available comic modules in multi\-column fashion. .TP \fB\-\-singlelist\fP List available comic modules in single\-column fashion. .TP \fB\-m\fP \fIMODULE\fP, \fB\-\-modulehelp=\fP\fIMODULE\fP Output module-specific help for \fIMODULE\fP. .TP \fB\-o\fP \fIOUTPUT\fP, \fB\-\-output=\fP\fIOUTPUT\fP \fIOUTPUT\fP may be any one of the following: .PP .RS .BR "html " \- Writes out an HTML file linking to the strips actually downloaded in the current run, named by date (ala dailystrips). The files can be found in the \fBhtml\fP directory of your \fBComics\fP directory. .RE .PP .RS .BR "rss " \- Writes out an RSS feed detailing what strips were downloaded in the last 24 hours.

A list of valid modules can be found by passing the .B \-l option. Multiple .I module arguments can be specified on the command line. Module names are case insensitive, and it is sufficient to specify a unique substring of the module name. .SH INDEX SYNTAX Instead of starting at the latest comic strip, an index lets dosage start at a certain strip. The index can be specified by appending a colon \fB:\fP and the index name after the module. Multiple comma-spearated indices can also be specified. .PP The index name itself usually is the part of the comic strip URL that identifiess a strip, eg. a number or a date. The expected format is documented when using the \fB\-\-modulehelp\fP option. .SH SPECIAL SYNTAX .TP .B @ This expands to mean all the comics currently in your \fBComics\fP directory.
