Adaptive CV allows to compile different variants of a CV (e.g., a résumé and an extended CV) from a single LaTeX source. It is particularly suitable for academic CVs but flexible enough to be used with any CVs.
Sleek Template is a minimal collection of LaTeX packages and settings that ease the writing of beautiful documents. While originally meant for theses, it is perfectly suitable for project reports, articles, syntheses, etc. – with a few adjustments, like margins.
It is composed of four separate packages – sleek, sleek-title, sleek-theorems and sleek-listings – each of which can be used individually.
