"""
Run a Stata do-file in the directory specified by **ctx.bldnode**. The
first and only argument will be the name of the do-file (no extension),
which can be accessed inside the do-file by the local macro `1'. Useful
for keeping a log file.
The tool uses the log-file that is automatically kept by Stata only
for error-catching purposes, it will be destroyed if the task finished
without error. In case of an error, you can inspect it as **do_file.log**
in the **ctx.bldnode** directory.
Note that Stata will not return an error code if it exits abnormally --
catching errors relies on parsing the log-file mentioned before. Should
the parser behave incorrectly please send an email to hmgaudecker [at] gmail.
**Careful**
The tool will not work if multiple do-files of the same name---but in
different directories---are run at the same time! Avoid this situation.
Usage:
ctx(features='run_do_file',
source='some_file.do',
target=['some_table.tex', 'some_figure.eps'],
deps='some_data.csv')
