3 # Hans-Martin von Gaudecker, 2012
6 Run a Stata do-script in the directory specified by **ctx.bldnode**. The
7 first and only argument will be the name of the do-script (no extension),
8 which can be accessed inside the do-script by the local macro `1'. Useful
9 for keeping a log file.
11 The tool uses the log file that is automatically kept by Stata only
12 for error-catching purposes, it will be destroyed if the task finished
13 without error. In case of an error in **some_script.do**, you can inspect
14 it as **some_script.log** in the **ctx.bldnode** directory.
16 Note that Stata will not return an error code if it exits abnormally --
17 catching errors relies on parsing the log file mentioned before. Should
18 the parser behave incorrectly please send an email to hmgaudecker [at] gmail.
22 The tool will not work if multiple do-scripts of the same name---but in
23 different directories---are run at the same time! Avoid this situation.
