"""
|
||||
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.
