# When package is changed, one should rerun this code to regenerate
# the vignette.  To change the vignette source code, change
# trac-example.Rmd.orig, not trac-example.Rmd (which is generated by
# running the code below).

# Using the approach described in
# https://ropensci.org/blog/2019/12/08/precompute-vignettes/
