- --disable-browser Disable the built-in file browser - --disable-color Disable color and syntax highlighting - --disable-comment Disable the comment/uncomment function - --disable-extra Disable the easter egg - --disable-help Disable the built-in help texts - --disable-histories Disable the saving of search strings and cursor positions - --disable-justify Disable the justify/unjustify functions - --disable-libmagic Disable the use of libmagic for determining a file's syntax - --disable-linenumbers Disable line numbering - --disable-mouse Disable mouse support - --disable-multibuffer Disable the opening of multiple file buffers - --disable-nanorc Disable the use of .nanorc files - --disable-operatingdir Disable the setting of an operating directory - --disable-speller Disable the spell-checker functions - --disable-tabcomp Disable the tab-completion functions - --disable-wordcomp Disable the word-completion function - --disable-wrapping Disable all hard-wrapping of text+ --disable-browser Disable the built-in file browser + --disable-color Disable color and syntax highlighting + --disable-comment Disable the comment/uncomment function + --disable-extra Disable the easter egg + --disable-help Disable the built-in help texts + --disable-histories Disable the saving of search strings and cursor positions + --disable-justify Disable the justify/unjustify functions + --disable-libmagic Disable the use of libmagic for determining a file's syntax + --disable-linenumbers Disable line numbering + --disable-mouse Disable mouse support + --disable-multibuffer Disable the opening of multiple file buffers + --disable-nanorc Disable the use of .nanorc files + --disable-operatingdir Disable the setting of an operating directory + --disable-speller Disable the spell-checker functions + --disable-tabcomp Disable the tab-completion functions + --disable-wordcomp Disable the word-completion function + --disable-wrapping Disable all hard-wrapping of textThere's also the --enable-tiny option which disables everything above, as well as some larger chunks of the program (like the undo/redo code and the code for selecting text).

And finally, there's always good old strip to remove all unneeded symbols.
