This package contains Nick Addington's recovery program and some related files and utilities. Since you're reading this, you've extracted the package to some directory, let's say 'foo/recover'. First, compile the programs: cd foo/recover/src make To be able to run the programs, add 'foo/recover/bin' to your search path. If your shell is bash, export PATH=$PATH:foo/recover/bin If your shell is tcsh, setenv PATH {$PATH}:foo/recover/bin To be able to read the documentation, add 'foo/recover/man' to your man path. If your shell is bash, export MANPATH=$MANPATH:foo/recover/man If your shell is tcsh and $MANPATH is not set, setenv MANPATH :foo/recover/man If your shell is tcsh and $MANPATH *is* set (less likely), setenv MANPATH {$MANPATH}:foo/recover/man You will probably want to add those two lines to your .bash_profile or .cshrc. The documentation is the place to get started: man recover man mkgraph man graphs man figures man board Or if you just want to see the thing run, mkgraph circles 2 4 | recover If you find any bugs, please e-mail adding@math.wisc.edu.
