Installing and running lsp (list species) on Linux
==================================================
1.  Make a new directory, lsp, and change to it.
2.  Download and untar the installer. 
    >tar -xzvf lsp****.tar.gz
    This will create /bin, /db and /docs sub-directories.
3.  The lsp binary should be in the /bin directory.
4.  lsp uses the ripgrep app (rg) for filtering and this should also be in the /bin directory.
5.  The /db directory contains standard PHREEQC database files, all encoded as UTF-8 compatible.
6.  Run 
    >bash ./install.sh
    to install the meld and diff apps if needed, and to copy the binaries to /usr/.local/bin.
7.  Close the existing terminal window and open a new one to update the paths.
8.  Ensure that the paths to lsp, rg and meld are set (i.e. ./local is in your path) and that the
9   lsp, rg and meld apps are working.
10. Change to the directory of interest.
11. Run lsp.

>lsp -r "*"
to see what is there. -r is for 'recursive; i.e. it will also search sub-directories.

>lsp -h or lsp -h1 or lsp -<option> for help.
