11. A system for using templates having associated metadata files, said system comprising: a computer; and at least one subsystem coupled to the computer for: parsing each of a plurality of metadata files, wherein each metadata file is associated with a template, wherein at least one of the metadata files determines an associated template's placement under a certain subcategory; storing a single file for each template in a UI (“User Interface”) accessible location comprising an associated template and associated code data based upon whether the template is a user-created template, a pre-defined template, an item template or a project template; building an index of all the templates; displaying the index in a customized UI, wherein the UI displays an identifier for each template in a format depending upon whether the respective template is a user-created template, a pre-defined template, an item template or a project template; receiving a selection of a template from the index; invoking a template engine upon the selecting of the template from the index, the template engine causing reading of a metadata file associated with the selected template, the metadata file including three sections, a TemplateData section that defines an appearance of the selected template, a TemplateContent section that defines content and creation parameters of the selected template and a ReplaceParameters section, wherein the metadata file provides information regarding the template contents and template creation process and wherein the metadata file determines whether data to be created will be created in a separate folder for the data, wherein the metadata file is created by using inference rules to index at least one file by determining elements of the at least one file to be generalized; creating a project according to specifications of the metadata file; performing parameter substitution to enable replacement of key parameters on template instantiation.
12. A system according to claim 11 wherein each template corresponds to a project in an integrated development environment (IDE).
