### I'm getting build errors when compiling the code

clip is writte in C++17 and needs a reasonably modern C++ compiler and standard

library. In most cases where the code doesn't build it's due to some problem with

the local build environment. We always appreciate bug reports so that we can

improve our build system on GitHub Issues.

### The test suite fails on my machine because text placement is slightly offset

The test suite requires that you have the original Microsoft Arial TTF files

installed on your machine. To verify that this is the case, run `fc-match

'Arial,Helvetica,Helvetica Neue:style=Regular,Roman'` and check that it returns

the correct 'arial.ttf' file.

### What happened to the project name?

The project was started in 2011 and was initially called "FnordMetric". The

first version from 8 years ago also included facilities for storing and

transforming data in addition to the charting code. Over time, the data

processing parts were removed, leaving only the plotting code. However, as a

consequence, most of the search queries for the project name would return

outdated information, resulting in a generally confusing and stale-feeling

situation. The best solution seemed to be to rename the project and so, after

going a few other candidates (about which people complained), we finally settled

on 'clip', since it was short, pronounceable, easy to remember and unencumbered.
