%description
A trimmed down copy of the "kent-core source tree" turned into a 'C'
library for manipulation of '.2bit' files. See
<https://genome.ucsc.edu/FAQ/FAQformat.html#format7> for a quick overview
of the '2bit' format. The "kent-core source tree" can be found here:
<https://github.com/ucscGenomeBrowser/kent-core/>. Only the '.c' and '.h'
files from the source tree that are related to manipulation of '.2bit'
files were kept. Note that the package is primarily useful to developers
of other R packages who wish to use the '2bit' 'C' library in their own
'C'/'C++' code.
