Example of use

In order to compile PUQ you can use the following setup script.

./setup.sh -b -t      # build and test
sudo ./setup.sh -i    # install `puq` executable into bin directory
...

Compiled PUQ executable can be then run directly from a terminal.

puq -h                 # display help
puq -i "J/s"           # expression information
puq -c "12*J" "erg"    # conversion of units
puq -c US "yd" SI "au" # conversion between unit systems
...

Lists of all units, quantities and unit sytems are accessible using -l flag:

puq -l base
puq -l US deriv
puq -l AU quant
