Basic Config Generation Tool (search and replace)

We need a basic and flexible config generation tool which takes template files and searches for certain spaceholders which it then replaces with values given in a settings file. The tool should have the following characteristics: - be written in Perl and should work on Windows as well as Linux - the source code has to be fully documented - the settings file (see example [login to view URL] attached) includes a variable “$TEMPLATES” which includes the directory where the template configuration files are stored, a sample of such a settings file and template configuration files has been attached - next in the settings file, the variable $CONFIGS includes the directory where the final config files should be stored - next in the settings file, we define various spaceholders like “%XX%”, “%X%” or “%MM%”, so the tool should search for these spaceholders in the configuration template file and replace it with the corresponding value behind the spaceholder - every value behind the spaceholder corresponds to a new set of configuration files, so for instance the template directory includes two files “[login to view URL]” + “[login to view URL]” and there are 17 different values behind the spaceholder, this means the tool will generate 17 times 2 configuration files e.g. [login to view URL], [login to view URL], [login to view URL], [login to view URL], [login to view URL], [login to view URL] etc. - the spaceholder %XX% will also be used to replace the “XX” in the name of the config template file - the tool should be able to handle up to 100 template config files which are stored in the template directory - the tool should be able to handle up to 100 spaceholders which are defined in the settings file - we should be able to use any type of character for the values, the only exception should be “space” which is used as a separator between the different values - if there are any limitations in the characters which we are able to use in the settings file then this should be clearly described - we welcome any ideas on better structuring the settings file or the whole process Our main evaluation criteria for nominating this project are - that you can show us that you fully understood our requirements and explain how you will meet these requirements - experience and references doing similar projects - the time required to finish the project
