-Linux and Mac: You will now have the binary distribution in a folder called `vsearch-2.20.1-linux-x86_64` or `vsearch-2.20.1-macos-x86_64` in which you will find three subfolders `bin`, `man` and `doc`. We recommend making a copy or a symbolic link to the vsearch binary `bin/vsearch` in a folder included in your `$PATH`, and a copy or a symbolic link to the vsearch man page `man/vsearch.1` in a folder included in your `$MANPATH`. The PDF version of the manual is available in `doc/vsearch_manual.pdf`. Versions with statically compiled libraries are available for Linux systems. These have "-static" in their name, and could be used on systems that do not have all the necessary libraries installed.
