ascii text format

hello.
i need to format some texts for they appear in the center of the page when opened in a browser, but i dont want to use HTML for format them, i just want to add tabulation to my txt files.
what soft can i use for format my txt files? there is command on VIM like "set textwidth" but this is not for me. any help i appreciate.

 

i think you can use any text editor which has it's own script system, for example Notepad++ (just press Record -> format first line -> turn to next -> press Stop -> and then run recorded script)

 

this are called macros, since when macros should be a solution?
macros objective is to automate tasks, should them be for automate text formattion?
all i need is to get text formatted just like unix man pages are.
so, i checked this option on man

i dont know whether this can be a solution, i only ask because certainly someone has the right simple answer.

 

Yes, I've tried this method.

 

i dont think this method is the ideal solution, at least not very pratical.

 

In my opinon it is, cause there are special macroses to make one formattion in the whole text.

 

maybe it is, however i dont believe most of formated *.txt texts you see on the web are formatted using this method.
