%description
A simple set of wrapper functions for data.table::fread() that allows
subsetting or filtering rows and selecting columns of table-formatted
files too large for the available RAM. 'b stands for 'big files'. bread
makes heavy use of Unix commands like 'grep', 'sed', 'wc', 'awk' and
'cut'. They are available by default in all Unix environments. For
Windows, you need to install those commands externally in order to
simulate a Unix environment and make sure that the executables are in the
Windows PATH variable. To my knowledge, the simplest ways are to install
'RTools', 'Git' or 'Cygwin'. If they have been correctly installed (with
the expected registry entries), they should be detected on loading the
package and the correct directories will be added automatically to the
PATH.
